Property-modified sintered alumina

Product introduction:
  Property-modified alumina is a newly developed alumina-based and magnesia containing heterogeneous material, possessing excellent properties of both corundum and spinel. When used in alumina-spinel castable in place of regular tabular alumina, the interfacial bonding betwwen aggregate and matrix can be enhanced, thermal expansion coefficient reduced, and other properties including strength, thermal shock resistance, spalling resistance, slag resistance and service performance comprehensively improved.
