Metal tungsten carbide powder has a good conductive thermal conductivity and high melting point. It is an important raw material for the preparation of tungsten carbide, which can be heated by a mixture of tungsten and carbon.
Preparation
Metal tungsten carbide powder can be heated by a mixture of tungsten and carbon, and the presence of hydrogen or hydrocarbons can accelerate the reaction. If use oxygen containing compounds in the preparation of tungsten, vacuum products must eventually in 1500 ℃, and to remove carbon oxides.
Origin
The annual production of tungsten carbide powder mainly for domestic use, some exports to Japan, the United States, Germany, Italy, France, Sweden and other countries.
Application
Metal tungsten carbide powder is an important raw material for the preparation of tungsten carbide. It can produce tungsten carbide materials with high hardness, are widely used in mining tools, deformation tools, wear-resistant parts and processing of cast iron, non-ferrous metals and non-metallic materials cutting tools.
