| Other | Sintered silicon carbide is created when prepressed and very soft SiC granulate is sintered at a temperature of more than 2,000 °C, when very strong sintering bonds between the material grains are formed. Firstly, there is lattice densification, then the porosity is lowered, and finally, sintering bonds between the grains of SiC are formed. This firing process has considerable product shrinkage of about 20 %. The final material is single-phase with higher hardness, heat and chemical resistance than SiSiC. | |
