The basic requirements for insulating ceramics are small dielectric constant, low dielectric loss, high insulation resistivity, high electrical strength, high mechanical strength, good thermal shock resistance, stability of humidity and frequency, etc., then the role of insulating ceramics And what are the characteristics? Next, Pintejin Ceramics will introduce to you.
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 condensers, ceramic components of microwave tube transport windows and various ceramic substrates.
Soap porcelain uses natural mineral talc as the main raw material, and then stubbornly becomes the most important crystal phase of ceramics, with good dielectric properties, and low price.
The disadvantage is that the thermal expansion coefficient is large, the thermal stability is poor, and the strength is higher than that of aluminum porcelain. Talc porcelain is usually used to manufacture belt switches, sockets, adjustable capacitors and shafts, porcelain plates, coil bobbins, and variable inductance bobbins.
The characteristic of insulating ceramics is that the thermal conductivity is lower than that of beryllium oxide ceramics at room temperature, but as the temperature increases and the thermal conductivity slows down, the thermal conductivity of boron nitride ceramics exceeds that of beryllium oxide ceramics, and it also has good electrical properties. performance.
And because of its low hardness (Morse hardness is 2), it can be arbitrarily worked or cut into different shapes, boron nitride ceramics are especially suitable for the production of thermal ceramic components and insulating ceramic parts for electronic devices.
Use at high temperature, such as the socket for high-power transistors, housings, radiators, semiconductor packaging cooling substrates and various high-temperature, high-frequency insulating ceramic sheets.
