Tungsten disulfide (WS₂) is considered to be a promising anode material for lithium ion batteries. It is not only cheap and safe, but also has a unique two-dimensional layered structure. The weak van der Waals force links the layers, which is conducive to the rapid diffusion of lithium ions in active materials.

90 Sr is an important heat-releasing nuclide in fragment solution. Separation of 90 Sr from fragment acidic solution can greatly reduce the cost of subsequent treatment of radioactive waste liquor. However, the separation of 90 Sr from fragment acidic solution is a very challenging task.

Tungsten trioxide, as a catalytic material for hydrogen production from water decomposition, has the advantages of photoelectric double response effect, stability, low light-on voltage, high hydrogen production efficiency, and is also a good electrochromic material.

Ultra-fine cemented carbide made of ultra-fine tungsten carbide powder has high strength and high hardness, which effectively solves the contradiction between hardness and strength of traditional cemented carbide. It is widely used in the manufacture of integrated circuit board micro drill bits and dot matrix printing. The table machine prints needles, precision tools, difficult-to-machine materials, woodworking tools, medical drills, etc.
