Some researchers prepared tungsten disulfide ultrafine powder by liquid phase precipitation method using sodium sulfide and sodium tungstate solution as raw materials. The obtained WS2 powder has good dispersion and uniform particle distribution.

High purity coarse tungsten disulfide powder refers to tungsten disulfide (WS2) powder with a purity greater than 99.9% and a larger particle size. The specifications of high-purity coarse tungsten disulfide can be WS2 powder with a Fischer particle size F.S.S.S of 1.9 μm and a laser particle size of 15-18 μm; Or WS2 powder with a Fischer particle size F.S.S.S of 3.8 μm and a laser particle size of 20-24 μm; Or a WS2 powder with a Fischer particle size F.S.S.S of 5.0 μm and a laser particle size of 25-28 μm, and so on.

High purity ultrafine tungsten disulfide refers to tungsten disulfide (WS2) powder with purity higher than 99.9% and small particle size. The specifications of high-purity ultrafine tungsten disulfide can be WS2 powder with a Fischer particle size F.S.S.S of 0.4-0.7μm, laser particle size of 3-4μm, or WS2 powder with a Fischer particle size F.S.S.S of 0.8-1.1μm and laser particle size of 9-10μm, etc.

Cemented tungsten carbide (W₂C) has attracted great attention due to its properties of high hardness and good wear resistance. It is mostly applied to the metallurgy, drilling, and mining industries under harsh conditions of high-pressure, high-temperature, and corrosive environment. The mechanical properties such as hardness, compressive strength, and transverse rupture resistance depend on the composition and microstructural parameters including the grain size. The reduction in scale of the microstructure also means an increase in the dislocation density and the amount of grain boundaries per unit area.

Tungsten and Copper (W-Cu) composite powder has a wide applications in electronics, electromechanical, military, and aerospace and other industries. This is due to its excellent thermal and electrical conductivity. The properties of these powders are dependent on their composition, characteristics of the starting powders and its synthesis procedures.

The main application of tungsten carbide (WC) is the production of hardmetal, or cemented carbide Cemented carbides are composite materials consisting of a hard phase (WC) and a metal, Hardmetal is used for cutting, drilling and wear resistant pieces. Tungsten carbide used for producing hardmetal is conventionally synthesized by heating a mixture of metallic tungsten powder and carbon black in a graphite furnace under a flowing hydrogen atmosphere. The carburization reaction is described as a solid state reaction between W and C. This reaction is re- markably dependent on the diffusion of C in W. There- fore the reaction temperature is high and lies in the range 1400–1800°C. This technique is able to produce WC powders with a wide range of mean particle sizes.

Tungsten rubber medical glove is high-density polymer tungsten glove having excellent radiation protection properties, which is fabricated using rubber as the matrix and tungsten powder as the filler. According to the experts, the radiation shielding capability of a substance is related to its atomic number and material density. The higher the atomic number and the greater the material density, the better the shielding performance.

Polymer tungsten curtain is a kind of protective curtain made of a new radiation protection material - a composite material of tungsten powder and high molecular polymer (one or more of plastic, rubber or thermoplastic elastomer). According to the experts, polymer tungsten curtain is an important radiation shielding in a mobile CT scanner.

The experts proposed a preparation method of polymer tungsten. The prepared polymer tungsten has good physical and mechanical properties, good weather resistance, chemical resistance and organic solvent resistance so that it has a wide application such as radiation shielding, vibration isolation, counterweight, and ordnance, etc.

Tungsten resin curtain is the most popular radiation shielding curtain that is mainly applied for mobile CT scanner to shield X-rays and other radiation sources. It is reported that tungsten resin is a new type of lead-free radiation shielding material (radiation protection material). And it is said that such a soft material of tungsten is likely to replace lead in medical shielding.
