What is the thermal conductivity of alumina ceramics? How to detect?
Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, which is used in 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 properties, it has been widely used in modern society and meets the needs of daily use and special properties.
Remember, when it comes to reliability, durability, and performance, our alumina ceramic tube stands tall, ready to transform your operations. Choose excellence, choose our Improvement of Alumina Ceramic Processing Method.
Because the alumina ceramic tube has many characteristics that other conduits do not have, many people prefer to choose it, which is one of the reasons for its rapid development in recent years.
What is the thermal conductivity of alumina ceramics? How to detect?
Thermal conductivity of alumina ceramics: material—thermal conductivity (W/m?k) Alumina ceramics—29.3 Beryllium oxide ceramics—196.8; about thermal conductivity can reach 30W/M*K, boron nitride, aluminum nitride prices are relatively high , 200 yuan/KG, thermal conductivity can reach 100-200W/M*K. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. Its thermal conductivity varies greatly with temperature. The thermal conductivity test requires the selection of the laser flash method.
