Corundum Ceramics
Corundum ceramics are produced from tabular corundum, offering high density, excellent thermal shock resistance and acid & alkali resistance features. Corundum ceramics have long service life and can be used under 1200-1800°C for a long period.
Application: crucible products can be used for non-metallic sample analysis and melt; corundum tube can be used in high temperature vacuum furnace, wire coil for heater and tin bath tube of float glass; corundum plate and pad can be used for powder metallurgy sinter.
