Customized Electrical insulation precision grinding and polishing temperature-resistant high-purity alumina ceramic substrate
Alumina ceramic (Al2O3) is a kind of structural ceramics characterized by high insulation resistance, voltage resistance, high strength, excellent thermal conductivity, low dielectric loss, and stable electrical performance. It is widely utilized in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, porcelain devices, spark plugs, and other industrial applications.
