Customized Industrial Square 99% 99.5% Alumina Ceramic Plate

The specification of square alumina ceramic plates

1. Material: It can be zirconia, silicon nitride and silicon carbide besides high purity alumina;

2.Shaping (forming) methods: it regularly include dry pressed, isostatic pressed and hot pressed;

3. Available geometries:  both sides can be  flat, one side or double sides with concave-convex;

4. Dimension capability: largest side-length up to be 600mm by 500mm, min. thickness to be 0.25mm

5. Precision process: double sided grinding, lappening, tapping, drilling, grooving

6. Accurancy feasibility: flatness to be 0.005mm, tolerance can be 0.01mm or better.

7. Surface treamt: polishing, glazing, metallizing, blasting or customized surface finish 

The main features of square alumina ceramic plates

1. Good surface roughness, even if flatness of large size ceramic sheet to be 0.005mm after precision grinding

2. Good thermal shock resistance, greater than 220 T(℃) under rapid raising temperature and cooling

3. High thermal conductivity of 96% alumina, up to 24 W/m.k at 25℃, It's fit for heat insulation application

4. High dielectric strength, low dielectric constant and dielectric loss. It's an ideal material for insulation fileds.

5. High temperature resistance, the max. service temperature can be 1750℃ in the oxide condition, but up to 2200℃ in the inert atmospheres.   

6. It owns excellent chemical stability, even if it  can survive in most of strong acids and alkalis. Also, it's resist aging.                 

The description of square alumina ceramic plate

The industrial ceramic plate is made of high purity alumina which is formed by dry pressed with very dense and smooth ceramic body. A wide range of customized shape are available, irregularly including square, rectangular, triangle, pentagonal, round, half circle and so on.  We offer small size to large size alumina ceramic plate in  an selection of thickness range from 0.25mm to 30mm, the max. side-length can be 600mm by 500mm. Moreover, we manufacture industrial ceramic plate in different raw materials, mainly including zirconia, silicon carbide, silicon nitride and aluminum nitride.

In addition, we also manufacture a variety of other technical ceramic components, including metallized ceramics, high precision structural ceramic components, ceramic grinding mechanism, pepper mill mechanism kit, ceramic seals, ceramic tubes.  In order to meet customers' stiff application, different surface treatments and precision secondary process can be performed to reach customers' specific needs.
