What is the meaning of Ceramic AD97 ceramics? Refers to: alumina ceramics have 97 porcelain (97% Al2O3), alumina ceramics (alumina ceramics) is a ceramic material with AL2O3 as the main body. Used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a ceramic with a wide range of uses. Because of its superior performance, its application in modern society has become more and more extensive, meeting the needs of daily use and special performance.

The main component of alumina ceramics is Al2O3.

People usually refer to ceramics with Al2O3 content greater than 75% as high-alumina porcelain.

Alumina porcelain is the most widely used ceramic in structural ceramics.

Because aluminum oxide ceramics have excellent electrical properties at high frequencies, they have low dielectric loss, large volume resistivity, high strength, high hardness, small linear expansion coefficient, and good wear resistance and heat resistance.

Alumina ceramics include 97 porcelain (97% Al2O3), 99 porcelain (99.99% Al2O3) and so on.

A characteristic of alumina ceramics is that its mechanical and electrical properties are improved with the increase of alumina content, but its shortcoming is that the increase in alumina content is accompanied by the increase in firing temperature, which gives the sintering process Bring some difficulties.

Therefore, it is more economical and practical to use 97% ～ 97% alumina porcelain in general occasions.

For those with particularly high performance requirements, 99% -99.99% alumina porcelain is used.
