The purity of high purity superfine tungsten powder is over 99.99%, less impurity content, appearance is silver, color uniform, with the characteristics of high density, high purity, high hardness, can be produced by plasma method.
Application
High purity superfine tungsten powder can be used in special high temperature devices, large scale integrated circuits and semiconductor transistors.
Preparation
High-purity ultrafine tungsten powder can be produced by plasma method, particles of tungsten powder prepared from the method are of good quality, clean, less pollution, small size, narrow size distribution, and the resulting powder spherical tungsten powder particles, spherical tungsten powder compact in the process of sintering shrinkage is very uniform, good size control can be realized.
