Customized 99% Alumina Ceramic Plate Al2o3 Ceramic Sheet For Mining
1). 95% alumina or steatite ceramic.heat compression molding,the alumina has been to improved insulation and mechanical strength.
2). The ceramics have no cracks,no burrs,no pinholes,no gaps,and no impurities, surface is smooth, dye absorption is passed.
3).Linear dimension tolerance ≤ ± 0.05mm, diameter tolerance ≤ ± 0.1mm, hole size distortion ≤ 0.05mm, circumference deformation size ≤ 0.1mm.
4). Insulation Resistance ≥ 100MΩ (have been checked by megohm in DC500V).
5). Dielectric Strength: AC2000V/50HZ/1min no breakdown phenomenon.
6). Linear expansion coefficient is slight,and less than 7.0 × 10-6mm /°C, and good for thermal shock performance.
7). Sintering temperature is 1350 °C, the use of a temperature not lower than 1100 °C, good corrosion resistance.
|Alumina ceramic is kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, 200T isostatic pressing and extrusion productive technology etc.
