2. Dimensional capability: the side length to be 500mm x 600mm, the thickness can be 0.15mm to 30mm
3. Surface treatment: lapping, fine ground, diamond-like polished to be Ra0.05, metallization, glazed
The description of alumina ceramic sheets
We have been making alumina (Aluminum oxide, Al2O3) ceramic sheets for over 12 years under rigorous quality control with carefully selected high purity ceramic materials ranging from 95% to 99.8%.
All these alumina sheets offer extraordinary properties of electrical insulation, thermal conductivity, breaking strength, and high-temperature resistance. Furthermore, one of the unique properties is its superb surface roughness to be Ra0.2 which results in excellent adhesion strength with a thin film and thick film metallization due to fine particles. Also, it can play a critical role in the sintering process which works as an alumina ceramic setter.
The regular forming methods we use include tape-casting, isostatic pressing, dry pressing. We are dealing with a variety of selection of thicknesses from small-size to large-size capability. With our comprehensive types of manufacturing types of equipment, we have the capability from prototyping to mass production in the short term.
