what’s property modified tabular alumina sinterd corundum
Property modified sintered corundum is a new type of alumina-based magnesia composite material that combines the excellent properties of both corundum and spinel. When used in corundum-spinel products as a replacement for sintered corundum, this product enhances the interfacial bonding between the aggregate and the matrix, reduces the thermal expansion coefficient, and improves the product’s strength, thermal shock resistance, spalling resistance, slag resistance, and service life.
