Alumina ceramic is a high-performance ceramic material made from alumina as the main raw material through processes such as crushing, forming, and sintering. Its main characteristics include high hardness, high wear resistance, high heat resistance, high insulation, etc. It is an engineering ceramic with a wide range of applications. Aluminum oxide ceramics have high insulation performance and good thermal conductivity, which can be used to make high-frequency ceramic media, electronic ceramics, thermistors and other electronic components, and are widely used in high-end electronic products.
