Ammonium paratungstate (APT) is a white crystalline powder with low water solubility used in the production of tungsten oxide, metal tungsten powder and tungsten acid.

Tungsten trioxide (WO3) is a chemical compound composed of tungsten and oxygen. It is one of the most common and stable forms of tungsten oxide and has several important applications. Chemical Composition: Tungsten trioxide has the chemical formula WO3, indicating that it consists of one tungsten atom (W) and three oxygen atoms (O).

Tungsten metal powder is a powdered metallic tungsten, which is a raw material for the preparation of tungsten processing materials, tungsten alloys and tungsten products. It is a grey-black metal with metallic luster.

Tungsten carbide powder is the main raw material for the production of cemented carbide, chemical formula WC. Tungsten carbide powder is a black hexagonal crystal with metallic luster and hardness similar to diamond. It is a good conductor of electricity and heat.

Tungsten metal bars are tungsten square bars or tungsten round bars made of tungsten powder through the densification process such as powder blending, pressing and sintering.
