Spherical tungsten carbide powder is an important raw material for thermal spraying. Some scholars have proposed an improved method for the manufacture of spherical tungsten powder:

Tungsten has an atomic number of 74 and a density of 19.35g/cm³. It has good radiation shielding properties and does not generate secondary electron radiation. It is ideal for nuclear radiation shielding materials. The tungsten shield preparation are as follows:

In the field of hard alloys, coarse-grained carbides have a series of advantages such as less structural defects, high micro-hardness and low micro strain. It is widely used in rock drilling tools, oil drilling tools, stamping dies, wear-resistant and corrosion-resistant parts, high temperature and high pressure endurance, metal pressure processing tools, rolling rings for steel rolling, and hard surface materials.

Waste tungsten oxide including unqualified blue tungsten oxide and tungsten trioxide. Ammonium tungstate includes ammonium tungstate solution, ammonium paratungstate, ammonium metatungstate etc.

Cerium tungsten alloy wire is a promising electrode material. Compared with traditional thorium tungsten alloy wire, cerium tungsten wire has the advantages of low electron emission work, high emissivity, high luminous efficiency and low arc voltage. The most important thing is that there is no radioactive contamination. It is the general trend to replace thorium tungsten alloy wire.

Tungsten has good electrical conductivity, escaping work near the silicon band gap and excellent thermal stability. It has become the first choice material and is widely used in grid materials and wiring materials of integrated circuits.

Organic hydrazine tungstate, the formula is 5(N₂H₅)₂O•12WO₃(also call auto reducing tungstate, abbreviated as ART). Ultrafine tungsten powder can be prepared by hydrogen reduction using ART. In solutions containing tungstate, the generation of ART is based on the following reactions:

In the existing market, the price of high-performance ultra-fine tungsten carbide powder is about one to two times that of ordinary micron-sized tungsten carbide powder, and the production costs of both are basically the same. Therefore, the production of ultra-fine tungsten carbide powder is a effective way for tungsten upgrading.

Tungsten electrode made of tungsten is widely used for welding because of its high melting point, corrosion resistance, high density, good heat conduction and conductivity. It is especially suitable for TIG welding and other electrode materials similar to this kind of work.

At present, MIM has become the most promising near-net-size forming technology in the international powder metallurgy field. It is known as one of the “hottest metal parts forming technologies in the world”. The metal powder injection molding technology (MIM) is a plastic molding process.
