The crystals of semiconductor material such as silicon carbide are used with the ceramic binder, and both are pressed between electrodes, and the entire crystal is sintered at a higher temperature. The temperature of manufacturing and sintered temperature plays a vital role in shaping electrical characteristics of varistors.
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.

Varistor - Wikipedia
On long loops, the varistors maintained a relatively high resistance and did not alter the signals significantly. Another type of varistor was made from silicon carbide by R. O. Grisdale in the early 1930s. It was used to guard telephone lines from lightning.
