Analysis of rare earth functional materials industry development

1 , the status of rare earth permanent magnet material in the wind power industry and the future

Wind power is one of the important applications of rare earth permanent magnet materials . The current global wind power capacity has more than 200 million kwh . 2012 , and the total net China reached 60.83 million kwh of wind power generating capacity reached 100.4 billion kwh . However, due to over-expansion and the sharp rise in raw materials such as rare earth elements , wind power equipment overcapacity of 260% .

The two main generators in the world today is the doubly-fed generators and direct-drive generators. In the doubly-fed generator cost generator group accounted for 7% of the entire unit , while the cost of direct-drive turbines in generators accounted for 31.5% . That is, for direct-drive turbines , the cost of the generator can not be more than 31.5 %. If the price of rare earth permanent magnet materials to maintain long-term stability and can be applied enterprise acceptable, permanent magnet direct drive wind power technology will become the future mainstream market technology. If rare earth prices, beyond the tolerance range of enterprise applications , then wind power manufacturers may turn to the use of medium-speed high-speed permanent magnet electric field or a traditional double-fed technology.

2 , rare earth luminescent materials industry development

In recent years , applications of rare earth luminescent materials continues to expand , mainly rare earth luminescent materials for energy-saving lamps with rare earth luminescent materials , display materials and special light rare earth luminescent rare earth luminescent materials . As the state continues to support efforts to strengthen the policy , expected by 2015 , the market demand for rare earth luminescent materials will increase every year. However, due to the impact of the global economic downturn , lack of market demand for energy-saving lamps , plus part of the stockpile in 2011 needs to digest , 2012 global light rare earth phosphor production fell sharply , down 4,500 tons estimated in 2013 will continue to be sluggish , down to about 4200 tons . In the long run , with the lower aspects of the introduction of the policy to promote energy-saving lamps and fluorescent prices, future demand for lamp phosphors may gradually recover. Major world lighting trichromatic fluorescent lamp manufacturers have Philip, United States OSAM, Korea APN, and Tokyo , Japan Nichia Chemical , China Rainbow , Jiangmen Branch constant and Hangzhou Ming . With the implementation of the global plan to phase out incandescent , energy saving lamps will usher in a new development opportunity. However, due to the influence of rare earth prices and other factors, the U.S. and Europe and other places of light rare earth phosphors have been discontinued or rarely yields, the future of China Resources Enterprise type lamp phosphors may be more competitive and anti-risk ability .

Rare earth phosphor display including CRT, CCFL and PDP. As a traditional CRT display after 60 years of development and use of rare earth phosphors , has now entered a period of recession , basically out of the market . CCFL backlight used to be the main technology , has now been replaced by LED technology. The current global PDP shipments remained at around 15 million -1700 million, or approximately 450-500 tons of phosphor required . Currently there are major producers PDP phosphor Nichia of Japan , the fundamental chemistry, chemical and other large electricity and Tokyo , and continents , such as South Korea's Samsung , China 's rainbow colored homes and Su Bote such as Beijing .

The main application areas are LED general lighting , landscape lighting and backlighting . According to the latest LED Engineering Research Institute survey data show that in 2012 China LED phosphor market sales increased by 70% , while sales increased by only 23% , mainly due to lower prices quickly cause phosphors companies generally do not appear increment increased profits phenomenon. At present , the domestic LED enterprises continue to increase , but the business is small , the product is only limited to the low-end market , high-end products still need to be imported. In the future , China's LED lighting industry to accelerate technological innovation, improve product quality to meet the needs of high-end market . The world's leading phosphor companies are: American Intematix, Japan fundamental chemistry, Germany LWB, German DIN materials research in Beijing , Beijing Nakamura Yuji , Subo Rui Jiang , Dalian Luming , Shanghai and Xiamen Keming Da Wei Tao and other companies .

3 , application status and development trends of rare earth catalytic materials

Currently , rare earth catalytic materials are mainly catalytic molecular sieve type rare earth materials, rare earth perovskite-type catalytic materials and ceria-zirconia solid solution type catalytic materials were used in petrochemical , environmental and chemical and automobile exhaust and other fields.

Application of rare earth catalytic materials in the petrochemical industry is currently using the maximum number of fields , about 100 million tons per year , of which the rare earth content of 2-6 % of the global consumption of about 3-4 million tons of lanthanum oxide and cerium oxide annually. Major foreign producers of Grace , Albemarle , BASF , JGC and Intercat so on. China 's large-scale enterprises in the petrochemical FCC catalyst Catalyst Company , PetroChina Lanzhou catalytic Company , Leshan run and , Jilin Jia float , Shanxi Teng Hui Mao and Qingdao City.

Rare vehicle exhaust purification catalyst for harmful substances can be converted into carbon dioxide and water , which is the most critical component of cerium oxide . Annual automobile exhaust purification cerium oxide consumed more than 11,500 tons . In addition , rare earth catalytic materials is also considered the most hope for the future , may be an effective method for large-scale purification of human living environment applied .

Other application areas include rare earth catalytic materials in the field of polymer materials , new energy application in the field of application of catalytic combustion and its application in fine chemicals and so on. Rare earth catalytic materials used in the new field of energy including fuel cell applications that can improve the energy conversion efficiency, achieve ultra-low or zero emissions of pollutants . Future , new energy catalytic material may be a new growth point . Future development can consume light rare earth catalytic materials as a key catalyst for the development direction of the rare earth industry , so you can more balanced use of rare earth resources.

4, the development and application of magnetic refrigeration technology status

Magnetic refrigeration technology is in addition to gas compression / expansion refrigeration , semiconductor thermoelectric effect absorption refrigeration and heat effects of phase change material outside of an emerging refrigeration , green refrigeration technology. Currently , the world attach great importance to the development of magnetic refrigeration applications , there are nearly 30 countries to carry out research and development work at room temperature magnetic refrigeration . United States and Europe , Japan, Russia and China and other countries have also carried out a magnetic refrigerator design and development work, and has made ​​great progress , foreign companies are expected within two years magnetic refrigerator will be available, mainly used in freezers and air conditioning.
