High Purity 99% 99.5% Alumina Ceramic Setter Plates

As setter plates, aluminum oxide ceramics offer critical advantages than traditional setters made from materials like both tungsten and graphite. They enable energy and cost-efficient processing of high-precision sintering components.
Ceramic setter plates and sintering trays help optimally arrange and secure molded parts in a sintering furnace to prevent undesirable deformations during the firing process. To ensure energy-efficient and precise process control when firing,
Our facility offers a wide range of materials made from aluminum oxide ceramics in different purities ranges from 95% to 99.8%, a selection of shaping methods will be adopted as per different thickness and dimensions, the regular forming methods are tape casting, dry-pressed and Isostatic pressed in our production, also all these ceramic setterplates can be manufactured according to customized designs and qualities with decisive advantage:

●High thermal conductivity

High thermal conductivity of Al2O3 results in homogeneous thermal distribution within the sintering components. Excellent thermal shock resistance is another added benefit, which enables faster firing cycles.
● 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.

● 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 surface also protects parts from contamination from the setters.

● 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 akalis.
● 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.

The specification of ceramic setter plates:

● Optional materials: aluminum oxide ceramics, Silicon Nitride Ceramics, silicon carbon ceramics

● Dimensions : max. size up to 400mm x 300mm, max. thickness to be 30mm

● Norminal tolerance:both length and width with ± 1% of dimensions, thickness with ± 0.5 mm

● Secondary process: precisely grinding, lapping, polishing, CNC machining, glazing and metallizing
