Propylene Tungsten Trioxide Preparing Tungsten Carbide Powder

The craft of Propylene tungsten trioxide prepare tungsten carbide powder improve the preparation of tungsten carbide powder level of technology, and the obtained tungsten carbide powder can be used in production, which makes China tungsten carbide powder resource become economic advantages quickly, it has made tremendous contributions in our primary mineral export situation.

Propylene (propylene, CH₂ = CHCH₃) is colorless, slightly sweet with gas. It is slightly narcotic, it has a full decomposition at 815 ℃, 101.325kpa. It dissolves in water, solubles in organic solvents, it is low toxicity substance. Propylene is the basic raw material of the three synthetic materials, mainly for the production of polypropylene, acrylonitrile, isopropyl alcohol, and acetone and propylene oxide.

Tungsten carbide powder has excellent properties of high melting point, high hardness, high fracture toughness and high compression strength, etc.; it is widely used as tools and materials and wear parts. The demand of tungsten carbide powder is so high that makes people concentrate more to study how to prepare the raw materials, the following describes a new tungsten carbide powder preparation process.

Propylene tungsten trioxide preparing tungsten carbide powder that is making tungsten trioxide and propylene as raw material, the raw material is placed at 450 ℃ -600 ℃ to heat, so that the tungsten trioxide fine particles deposited on the surface of carbon. Then in the mixed gas 90% Ar + 10% H₂ at 1100 ℃ -1400 ℃ , heating it about 2h, the materials are crushed to obtain tungsten carbide powder sifted.
