Tungsten carbide alloy powder has characteristics of high hardness, wear resistance, corrosion resistance, high temperature resistance, etc. It is an important tungsten carbide material and catalytic material with broad application prospects. It can be prepared by spray drying-fluidized bed method and fixed bed method.
Application
It is also an important catalytic and electroactive material. It exhibits good catalytic activity for some hydrogenation reactions, alkane cracking, catalytic reforming, and catalysts for fuel cells. Its catalytic activity is similar to that of platinum group elements, and is not poisoned by 10-6 mass concentrations of CO and H2S. It is a catalytic material with broad application prospects.
Preparation
Currently, various methods can be used to prepare tungsten carbide powders, including high-energy ball milling, fixed bed, spray drying-fluidized bed, plasma, in-situ carburizing, etc. The main application is pray drying-fluidized bed method and fixed bed method.
