Recently, Dyze Design, a developer of 3D printer accessories in Montreal, Canada, released its latest product, Tungsten Carbide Nozzle. This is an important accessory for ultra-high performance 3D printers. It offers high wear resistance and performance for almost any 3D printer brands such as Ultimaker, Prusa, Lulzbot, Raise3D and Robo. Its will greatly increase speed of printing, which means lower energy consumption and cost.

With the continuous development of material science, the structure of materials is developing toward two-dimensional direction, which provides an important way to give full play to the potential of materials. Thin film science is a very important field for the development of new materials and devices. Target is the key material in surface coating technology. The performance of target directly affects the performance of film, and the performance of target is mainly determined by the production process of target.

As a new type of wastewater treatment technology, photocatalysis can be widely used in the building decoration market and indoor vehicles. The photocatalytic process has almost no selectivity for the degradation of organic matter, and can completely mineralize organic pollutants without secondary pollution.  The unique advantages of simple equipment, low investment and good effect.

For a long time, China's tungsten concentrate mining is dominated by wolframite ore resources, and the output once accounted for more than 90% of tungsten concentrate production. At present, the reserves of wolframite ore have been depleted, and the replacement of black tungsten ore with scheelite concentrate is of great significance and imminent. 

Tungsten oxide is a new type of semiconductor material and one of the few oxide semiconductors which are easy to achieve quantum size effect. It has the characteristics of electrochromic, absorption and catalysis. It has been widely used in fuel cells, chemical sensors, optoelectronic devices and other fields.

Tungsten has the advantages of high melting point, high strength, high hardness and high wear resistance. In addition, it has low thermal expansion coefficient, good corrosion resistance and oxidation resistance, and good conductivity and thermal conductivity. Therefore, tungsten has been widely used in cutting-edge scientific fields, national defense industry and civil industry.

Tungsten carbide (WC) has been widely used in catalysis because of its platinum-like catalytic activity, high hardness, high thermal stability and good wear resistance. As a catalyst, WC has not only good catalytic activity for hydrogenation and dehydrogenation, but also selective catalysis for some reactions.

Ammonium paratungstate is an important intermediate product in tungsten hydrometallurgical process. The production process of tungsten concentrate decomposition-ammonium paratungstate mainly includes ore decomposition, transformation to obtain crude ammonium tungstate solution, impurity removal from crude ammonium tungstate solution, crystallization to obtain ammonium paratungstate and crystallization mother liquor, recycling of crystallization mother liquor, etc.

Foamed metal tungsten is a kind of material with double properties of function and structure. It has certain strength, high temperature resistance and corrosion resistance, and has low density, high porosity and large surface area. It is widely used in modern defense and military, atomic energy, aeronautical and aerospace, electronic information and other fields.

Molybdenum and tungsten resources are China's dominant resource minerals. China's reserves of molybdenum and tungsten resources, mining and processing volume, and trade volume occupy an important position in the world, while tungsten is in the first place. Tungsten mainly exists in the form of black tungsten and scheelite. The scheelite often contains a certain amount of molybdenum, which is usually in the form of molybdenum sulfide, which can be separated by conventional flotation methods. The tungsten resource containing molybdenum oxide is difficult to process. It is rarely used.
