Rare earth magnets are made out of rare earth elements or alloys. These are not rare in the real sense of the term. These are made from elements that are from the "rare earth" group. These became widely popular during the 70's and 80's. Earth magnets are regarded to be much stronger than the other magnetizers that are made of ferrite and alnico. These are thus capable of being used for a longer duration of time.

Earth magnets are widely popular as these are the preferred choice of many industries. Some of the most common applications of the same can be seen in computer bicycle dynamos, hard drives, audio speakers, and fishing reel brakes. Few other applications where this is used include diamagnetic levitation experiments, stop motion animations, wind turbines and roller coasters.

There are two categories of earth magnets - Samarium cobalt and Neodymium. The first one is the very first type of earth magnet that was developed. These cost more and are weaker in strength than the second type of magnet. This is why these have not been manufactured in large scale industries. It has a high curie temperature that ensures that its magnetic properties stay intact. It is used for manufacturing high speed motors and in different kinds of equipments. It also finds its use in the manufacture of some musical instruments.

Neodymium magnet is also referred to as NdFeB, Neo and NIB. It is a permanent element that was discovered in the 80's. Made of an alloy of iron, neodymium and boron, it is a strong magnet. It has a very high magnetic field strength and has a number of uses. As these are cheaper it finds its use in many different industries. It is used in the manufacturing of synchronous, stepper and spindle motors. It is also used for making couplings and bearings. Resonance imaging is another area where it is used.

These are 1.5 to 3 times stronger than the usual refrigerator magnets. These are available in a range of shapes and sizes. There are cylinder shaped, disk shaped, ring shaped and many other shapes to choose from. If used properly these magnets would serve a lifetime. These are much more powerful than the other horseshoe magnets that can be found in the market.

This is the most widely used rare earth magnet. Affordable and strong these do not lose their magnetism easily and can last for long. The magnets can be customized to suit individual needs. Customizing is easy and it is not at all costly to get the magnets personalized by the manufacturer.

Rare earth magnets are being increasingly used in children's toys as well. As these are much cheaper and less bulky, manufacturing companies prefer using these in children’s products.

Rare Earth Elements: Discovery and Early History

Details: Category: Rare Earth News; Published on Tuesday, 16 September 2014 13:57; Written by jwy; Hits: 2284

Rare earth elements are seventeen in number according to the periodic table. However, the word “rare” is not to be taken in a literal sense as most of these elements are readily available in the earth’s crust, and they are present in significant quantity. However, the reason the term rare is used is because the areas in which these elements are present can’t be easily extracted due to the unfavorable economic conditions of these areas. In this article, we will be looking at the discovery and the early history of these elements through the following 7 points.

1. The periodic table was not always in the position in which we see it today, as more elements were discovered they were added accordingly. The first time scientists came across the idea of rare elements was after the discovery of ytterbite, which was later renamed as gadolinite.

2. Ytterbite was then sent off to the University of Turku for an in depth examination. There, the professor after processing the element through different procedures was able to extract an oxide but was not able to place a specific identity to it. Also, no other elements were separated that are used to form the rare element in combination.

3. Later in 1803, a couple of scientists in an independent study discovered a white oxide, which they named as ceria. At the same time, another scientist named Martin Klaproth discovered the same element and gave it a different name, ochroia.

4. By this time, people were familiarized with the idea of rare elements. However, for nearly thirty years no other rare elements were discovered by scientists.

5. Later, more rare elements were found, from the same layers of the crust from which the first two rare elements had been discovered.

6. In the same period of scientific history, the famous Lanthana surfaced. This discovery was credited to Carl Mosander who separated ceria through heating the nitrate and then dissolving the resulting product in nitric acid. This process produced a raw form of Lanthana. It wasn’t for another three years after that time until pure Lanthana and didymia, both versions of the rare earth element, were discovered.

7. From here on forward, the discovery of rare elements picked up speed. A number of rare earth elements were discovered. It was by 1842 that the majority of the minerals were known to the people working in the field. At first this element was used for pure scientific reasons only, mostly for research in universities. However, with time, scientists discovered a number of other beneficial uses for these elements. They covered a huge base, from being used in making different parts in the aviation machinery industry to being used in a number of medical treatments that benefit humans. One example is the use of Lanthana in medicine for the renal failure.

Chinese Investors Look for Rare Earth Metals in Greece

Details: Category: Rare Earth News; Published on Tuesday, 16 September 2014 14:00; Written by jwy; Hits: 2202

The Greek subsoil and its rare earth metals have attracted the interest of Chinese investors. On the occasion of the ERES international conference hosted in Greece from September 4 to 7, a delegation from China, which is considered the absolute leader in the earth metals field, visited Greece.

It is estimated that 17 valuable minerals associated to the high-tech industry are present in Greece. The majority lies in the underwater area of the northern Aegean Sea and in Thrace.

Indications of rare minerals appear in the areas of Rhodope, Thessaloniki, Chios, Kilkis, and in the coastal and underwater area of Strymonikos Bay, and bauxites on the Greek mainland.

These earth metals can be used as catalytic automobile converters, in petroleum refining, in TVs, mobile phones, portable DVDs, laptops, rechargeable batteries in hybrid and electric cars, wind turbine generators, medical devices, photovoltaic systems, missile defense satellites and many more.

European geologists claim that Greece, along with Sweden, Finland, Norway and Denmark, have rare earth metal and mineral reserves, and should be used to save Europe’s car and electronics industries from uncertain imports.

Foreign resources to support Japan's rare earth imports or loose

Details: Category: Rare Earth News; Published on Monday, 15 September 2014 14:14; Written by HJF; Hits: 2364

Indian Prime Minister Modi during the recent visit to Japan for the Japanese enterprises to mine rare earth minerals in India gave the green light. Exploitation of India to resolve 15 percent of Japan's rare earth rare earth needs. Now nearly 90 percent of the rare earths, Japan needs to import from China. Keith Tanuo Fu stressed by China's rare earth export restrictions bitter fight to get rare earths in Japanese wherever possible.

He said: & ldquo; Japan had suffered in China. 2010 due to the East China Sea incident China stopped exports to Japan of rare earth. It is playing in Japan & lsquo; chest nest & rsquo ;. Japan will soon start in the world & mdash; & mdash; Africa, Latin America and Asia to look for other sources of rare earths. Also deep seabed looking for. Now again tentacles in India and Malaysia. & rdquo;

If the success of the project in Malaysia, to 2018 in Japan than China can ensure that 60 percent of rare earth sources. But cooperation with Malaysia accompanied by high risk, often broke environmental pollution scandal, for example, Malaysia Green who oppose Australian company, funded by Japan Lenas rare earth production plant in Malaysia. Due to serious pollution problems, Malaysia in 1992 closed the Japanese-funded rare earth processing plant. After 15 consecutive years in Japan for compensation for environmental pollution.

It is worth noting that China reducing rare earth mining, reduce export quotas, but also because of pollution problems. But the WTO does not recognize China this argument. This spring the WTO accusing China of raw materials in violation of trade rules. Japan jointly with the United States and the European Union had sued the Chinese. China promised to give the corresponding conclusions, but have had no reports of rare earth export quota increase. Keith Tanuo Fu believes that the Japanese expressed concern.

He said: & ldquo; course, Japan must therefore give yourself the insurance. Regardless of how the WTO decision making, when the situation is serious, it was too late. High-tech industry needs rare earths. However, the future trend is difficult to predict how the Japan-China relations. It is constantly being intensified stage. If held in November during the APEC summit in Beijing, the organization can succeed Shinzo Abe and Xi Jinping meeting, which will ease the Sino-Japanese relations to some extent. I have no doubt that the meeting will be held. Chinese people do not refuse to meet in Japan. China does not want to hold the APEC summit for the first time, let it accompany scandal. However, there may be only two leaders met mere formality. & rdquo;

In order to reduce dependence on China, Japan, the state-owned oil and gas company metallic minerals (JOGMEC) invested $ 700 million in Uzbekistan, Kazakhstan, Turkmenistan, Kyrgyzstan and Tajikistan rare earth exploration. But Chinese companies have operations in these countries. Visible, Japan in foreign markets also suffered China's rare earth strong influence.
