Zircona fused alumina is corundum containing 10%-40% zirconium dioxide. The raw material of aluminum oxide is alumina, which is made by smelting in an electric arc furnace at a temperature above 2000 °C. Do you know the main components and uses of zircona fused alumina?
From the perspective of mineral phase, zircona fused alumina is a kind of eutectic, which is formed by a-Al2O3 and Al2O3-ZrO2, and is its subcrystalline phase. There is also a small amount of glass phase in zircona fused alumina. According to the content of ZrO2, there are high, medium and low zircona fused alumina. Zircona fused alumina has a dense structure, a very tough texture, and good thermal stability.
Types and uses of zircona fused alumina products:
1. Segment sand, fine powder
Zircona fused alumina is a relatively advanced refractory raw material. Zircona fused alumina is an ideal material when making high-performance sliding nozzles and submerged nozzles. Zircona fused alumina can also be made into zircona fused alumina bricks for use in glass melting furnaces. It can be used as a high-grade building material.
2. Granularity sand
Zircona fused alumina has good melt erosion, so it can be used as a high-grade abrasive to grind steel, cast iron and various alloy materials. Zirconia fused alumina is also the raw material for heavy-duty grinding wheels, cutting discs, and high-speed abrasive belts.
3. Micropowder
Zircona fused alumina micropowder is also often found in abrasive paste, polishing wax, and emery cloth sandpaper.
