Modern insulating ceramic materials are widely used in the industrial field. Many electronic devices have particularly high requirements for the Alumina Ceramic Rod insulation of ceramic materials. What are the basic properties of insulating ceramics? Small dielectric constant, low dielectric loss, high insulation resistivity, high dielectric strength, high mechanical strength, good thermal shock resistance and other excellent properties,
Insulating ceramics can be used to manufacture insulating parts of ultra-high frequency and high-power electric vacuum devices, as well as ceramic shells of vacuum Alumina Ceramic Bar condensers, ceramic components of microwave tube transport windows and various ceramic substrates.
Insulating ceramics have different mechanical strength and resistivity according to their different components. With the continuous development of technology, alumina ceramics have been widely used in chemical industry, machinery manufacturing, biomedicine and other fields, and with the gradual expansion of application fields, It is of great practical significance to study the properties of alumina.
Alumina ceramics basically have no ductility and low toughness. In order to Alumina Ceramic improve the toughness of alumina ceramics, we add a certain proportion of zirconia to toughen alumina ceramics, which significantly improves the toughness of alumina ceramics.
Commonly used insulating ceramics include talc ceramics, mullite ceramics, cordierite ceramics, and forsterite ceramics. Among them, talc ceramics and mullite ceramics are the most widely used. The main crystal phase composition of talc porcelain is MgO*SiO2, which has the advantages of high mechanical strength, low dielectric loss, and good process performance. It can be used to manufacture most device parts. Typical high-frequency device porcelain for low cost and suitable for radio frequency bands. In some highly demanding integrated circuits, pure corundum porcelain with Al2O3 content of 99.9% is also used, and its performance is similar to that of sapphire single crystal.
