Physical properties of zirconium corundum
Zirconium corundum has a tough texture, dense structure, high strength, good thermal shock resistance, and is generally gray-brown. Uses of zirconium corundum: Zirconium corundum has good resistance to melt erosion. As an abrasive, it can make high-performance heavy-duty grinding wheels and has a good grinding effect on steel parts, cast iron parts, heat-resistant steel, and various alloy materials. ; In addition, zirconium corundum is also a refractory raw material and is an ideal material for making high-performance sliding nozzles and immersed nozzles. It can also be used to make zirconium corundum bricks for glass melting furnaces.
