Silicon Carbide and Alumina

In addition to alkali and zinc attack, the occurrence of molten iron and slag calls for SiAlON bonded materials – either the silicon carbide Sicanit® AI3 or the corundum-based Coranit 3S. The final decision depends on thermal conductivity requirement - low, to save energy, or high, to ensure a protective covering.
