Property-modified sintered alumina

Short Description:

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.

Size availability:

Aggregates and poders with sizes from 15 mm to under 45μm can be provided.

Product packaging:

25kg/bag, 1000kg/bag or other specific packaging as per users’ requirements are available.
