The Most Well-known Oxide Ceramic Material



Aluminum Oxide (Al2O3)


Alumina or alumina (Al2O3) is the main engineering material. It combines good mechanical and electrical properties. It is used more often than any other advanced ceramic material.


Alumina ceramic is a kind of ceramic material based on alumina (Al2O3). Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic washing is required. Alumina ceramics is a kind of widely used ceramics, because of its superior performance, in modern society has been more and more widely used to meet the needs of daily use and special properties.
