What are factors that affect the quality of silicon carbide bushings?

In the production of silicon carbide bushings, we often overlook some of the factors that can influence the quality of silicon carbide bushings, then what are these factors? 

1, Clay composition: The composition of clay is different, the clay products made of silicon carbide bulk density and compressive strength index will be different.

2, molding pressure: under the same conditions, different molding pressure on the quality of clay-based silicon carbide products will have an impact.

3, SiC particle size compositions: SiC particle size composition are also affected the quality of clay.

4, silicon carbide bushing bulk density, porosity, compressive strength and thermal conductivity and other quality parameters are important factors.
