3. Low thermal expansion coefficient: 5.3×10-6
4. Good flatness with uniform shrinkage at the firing process
3. Chemical stability, even in a harsh environment.
4. Minimal warpage, bending, and undulation.
7. Excellent resistance against oil and chemical.
8. Stable breaking strength, and less variance in shape or dimensions.

The specification of the ceramic setter plate
1. Material : 96% alumina, 99% alumina, 99.5% alumina, zirconia, silicon nitride, silicon carbide optional
2. Dimensional capability Side length max. 500mm x 600mm, Thickness can be range from 0.15mm to 30mm
3. Surface treatment:  natural surface, lapping, diamond-like polishing, metallization, glazed
4. We have many selections of al2o3 ceramic plates, refer to the checklist of standard size in different purity.Remark:
All the above big size ceramic setter tray can be cut to specific dimensions per customers' requirement.

The description of mullite ceramic setter plate
Mullite mainly includes two types which are the ordinary and high-purity mullite ceramic. The ordinary has the lower purity raw material, its components include A2O3, SiO2, TiO2, Fe2O3, CaO, MgO, Na2O, K2O, and other impurities, so it can be generally applied as refractories for less demanding on high-temperature strength occasions.
In terms of high-purity mullite sintered by the high purity SiO2 Al2O3 powders, It has the advantage with excellent refractory, uniform expansion, excellent thermal shock resistance, high load softening point, small high-temperature creep, high hardness, the chemical resistance. Especially the high-performance high-purity mullite ceramics, at 1300 ºC when bending strength of 570MPa, fracture toughness KIC of 5.7MPa, 1.6 times higher than normal, such as the temperature increases, the strength and toughness only do not decay but greatly improved, high purity mullite ceramics as a high-temperature material excellent material properties.
