Varistor - Wikipedia

2019-4-15 · 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.

Ceramic - Wikipedia

2019-4-15 · A ceramic material is an inorganic, non-metallic, often crystalline oxide, nitride or carbide material. Some elements, such as carbon or silicon, may be considered ceramics.Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
