Effects of Pre-Sintering Temperature on Tungsten Carbide Density
- Category: Tungsten Information
- Published on 13 November 2017
The pre-sintering temperature of tungsten carbide has a direct effect on the density. With the pre-sintering temperature increasing, the overall density of the green is increasing. But the change trend is different in different temperature range. When the temperature is low, the change depends on the density of volatile forming agent. At high temperatures, it depends mainly on the diffusion of atoms.
Relationship Between Green Strength and Pre-Sintering Temperature

- Published on 13 November 2017
The strength of tungsten carbide has a great influence on the green processing. Only when the strength is greater than 30Mpa, it can be processed. In the pre-sintering process, the strength directly depends on the pre-sintering temperature, so the temperature must be strictly controlled.
