Introduction of alumina ceramics:
Insulating ceramics refer to the ceramic materials used as installation, fixation, support, protection, insulation, isolation and connection of various radio components and devices in electronic equipment. Insulating ceramics require high volume resistivity, low dielectric coefficient, low loss factor, high dielectric strength, corrosion resistance and good mechanical properties.
Insulating ceramics are widely used in circuit substrates, packaging, high-frequency insulating ceramics and other industries. The main devices include insulators, spark plugs, resistor matrix materials and integrated circuit substrates.
