Alpha sintered silicon carbide – Mc Nally Institute
Self-sintered silicon carbide carries a slight price premium compared to the reaction bonded version. Although the preferred seal face material, it often is too brittle for some seal face designs. It is one of the most popular materials used in mechanical seal face design and is recommended in high temperature water or hot oil appliions because of its excellent thermal conductivity.

Recrystallized silicon carbide, like reaction bonded silicon carbide, can be infiltrated with silicon metal. However, the infiltration process occurs after the primary sintering. This grain structure not only provides excellent material properties, but also enables extremely precise manufacturing along with high purity used in industries like semiconductor production.
Silicon Carbide SiC Material Properties - Accuratus
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
