This paper describes the effect of metal powder addition to a standard fred ceramic kiln-furniture product. Different amounts and combinations of aluminium and silicon are tested. Small additions have the metals completely oxidised forming secondary mullite or corundum. Higher amounts and suitable combinations lead to the formation of SiAlONs in the core. In any case physical properties could be kept or even improved, especially cold crushing strength, even if the fring temperature is reduced compared to standard.
