Tungsten is China's advantageous resource. China's reserves and consumption rank first in the world. However, the high value-added high-end products of tungsten products are monopolized by foreign companies, especially tungsten heating elements and supports used in high temperature environments. Mainly relying on imports, domestic imitation products are poor in thermal stability, easy to deform, short in life and limited in application.

Tungsten-copper composite is one of the heat sink materials widely used in power devices. It has good thermal conductivity and thermal expansion coefficient close to that of Si, GaAs and other semiconductor cores. Density of composites is the main factor affecting the electrical conductivity, thermal conductivity and expansion properties of composites, and it is also the key technical index.

Bismuth tungstate (Bi₂WO₆) is a typical n-type semiconductor formed from octahedral WO₆ and Bi₂O₂ layers. Bi₂WO₆ has excellent chemical properties, unique ferroelectric properties, catalytic properties and magnetic susceptibility of non-linear dielectrics. Bi₂WO₆ is a good visible-light photocatalyst material.

Nano tungsten trioxide powder is an important industrial raw material, which can be used to prepare nano-tungsten powder and nano-tungsten carbide powder. In addition, nano WO₃ has a strong ability to absorb electromagnetic waves. It can be used as a good absorbent material in the utilization of solar energy and an important invisible material in the military.
