How to test the thermal conductivity of alumina ceramics
Alumina ceramics is a ceramic material with alumina (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 kind of ceramics with a wide range of uses. Because of its superior performance, it has become more and more widely used in modern society to meet the needs of daily use and special performance.
Jinzhou Yunxing Industrial Ceramics Co., Ltd. is a new material company specializing in the production of high-purity alumina ceramics, integrating material forming, sintering and processing. The company has cooperated with key domestic and foreign universities to research new projects for many years. Let me share with you what is the thermal conductivity of alumina ceramics? How to test?
Thermal conductivity of alumina ceramics: material-thermal conductivity (W/m?k) alumina ceramics-29.3 beryllium oxide ceramics-196.8; probably the thermal conductivity can reach 30W/M*K, boron nitride and aluminum nitride are relatively expensive ,200 yuan/KG, thermal conductivity can reach 100-200W/M*K.
