Product Description

 

High Pressures and Temperatures Al2o3 Ceramic Disc

 

An Al2O3 ceramic disc (Al2o3 95% 96% and 99.7%) refers to a ceramic disc made primarily from aluminum oxide (Al2O3), which is also known as alumina.ceramic discs are commonly used in industries such as electronics, aerospace, automotive due to their desirable characteristics.The Maximum dimension of ceramic plate is 138x138mm and the thickness of ceramic plate ranges from 0.25 to 1.0mm.

 

Alumina Ceramic Disc Features: > High reliablility and sfety; > High density and mechanical properties > High electrical and thermal loading perormances > Low dilelectic loss and other characteristics

 

Alumina ceramic substrate / plate specification:
10x10x1mm, 20x20x2mm, 40x40x8mm, 100x60x8mm, 150x150x12.5mm, 200x200x25mm etc.
Can be made according to your requirements.
