High Temperature Ceramics for Light-Weight Kiln Furniture
Alumina- and mullite-based materials for kiln furniture application of up to 1700 °C have been successfully developed. The materials show significantly improved thermomechanical properties in comparison to commercial benchmark products permitting the design of kiln furniture with reduced mass. This leads to significant energy savings in high temperature processes. It is demonstrated that the achieved improvement in corrosion resistance against lead-containing vapours increase the lifetime of the products considerably.
