 Alumina ceramic is a ceramic material based on aluminum oxide (Al2O3) and 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 ceramic is a widely used ceramic. Because of its superior properties, its application in modern society has become more and more extensive, meeting the needs of daily use and special properties.
