Supermicro tungsten carbide powder as a "micro-tungsten particle bullet", due to fine particles, permeability, good dispersion, bio-genetic engineering provides a new and effective method, can be prepared by one-step reduction carbonization.
Preparation
In the preparations of supermicro tungsten carbide powder, one step reduction carbonization method can be used in addition to the traditional process. One-step reduction carbonization method is a method suitable for industrial scale production, using the precursor powder containing tungsten as a direct step to restore carbonized tungsten carbide powder.
The continuous process of direct reduction carbonization can shorten the process, improve the efficiency of ultrafine tungsten carbide powder generated, at the same time the ultrafine tungsten carbide powder has better homogeneity and smaller particle size.
