Refractory High Purity Customized Al2O3 Ceramic Setter Plates
The prime features of the al2o3 ceramic setter plates
1. Surface Roughness
A desirable surface roughness ensures optimum gliding for sintered parts. The surface roughness is Ra < 1 µm makes it possible to achieve uniform shrinkage at the firing process, therefore helping to preserve the shape of the products. The smoothness of the surface also protects parts from contamination from the setters.
2. High thermal conductivity
High thermal conductivity of Al2O3 results in inhomogeneous thermal distribution within the sintering components. Excellent thermal shock resistance is another added benefit, which enables faster firing cycles.
3. High thermal resistance
It offers a positive effect on the energy-saving of the firing processes. Highly thermally resistant materials result in lower thicknesses of the setters, which improves energy efficiency because of less thermal ballast. In addition, ceramic setter plates can also be used at temperatures far over 1000°C.
4. Chemical stability
For ultrapure alumina (purity over 99%) can be used both in protective gas atmospheres and reduction atmospheres, They are also stable in reactive atmospheres and in hydrogen atmospheres, not react with most of strong acids and alkalis.
5. High mechanical stability
This property, paired with low thermal capacity, not only results in a lower weight with a reduced tray volume; it also retains very little residual heat during the cooling process. This has a positive impact on energy consumption during firing.
