Thermal characteristics:
Ceramic materials have high melting point (mostly in above 2000 ℃), and has excellent chemical stability at high temperature;The thermal conductivity of ceramics is lower than that of metal materials, and ceramics are also good insulation materials.At the same time, the linear expansion coefficient of ceramic is lower than that of metal. When the temperature changes, ceramic has good dimensional stability.
Electrical characteristics:
Most ceramics have good electrical insulation, so they are widely used to make insulation devices of various voltages (1kV~110kV).Ferroelectric ceramics (barium BaTiO3) have a high dielectric constant and can be used to make capacitors. A few ceramics also have the characteristics of semiconductor and can be used as rectifiers.
