Plate-shaped corundum is a dense crystal formed by sintering corundum material, made of pure alumina raw material, grinding, molding, drying, and quickly heating and cooling in a high-temperature vertical kiln. So what are the application industries of plate-shaped corundum? Today, the editor of Haixu Abrasives summarizes the application industry of plate-shaped corundum.
Plate corundum has high purity, good volume stability, relatively small heavy burning shrinkage, and the refractories or castables used for high-temperature treatment have good thermal shock stability and flexural strength, but the price is higher than other alumina.
Application industry for plate-shaped corundum:
1. Plate-shaped corundum has relatively high heat resistance, mechanical strength and wear resistance. It has high chemical purity, good insulation characteristics, and good acid and alkali corrosion resistance. Plate corundum is an aggregate selected for ambient and fixed high-performance refractory materials.
2. Plate-shaped corundum is an ideal refractory raw material. It can be used as aggregate in various aluminum refractory materials, or added to other aluminum amorphous refractory materials .
3. Any area where the electromelted corundum or white corundum can be replaced by plate-shaped corundum, and the performance of refractory materials can be improved. Widely used in steel, casting, petrochemical, ceramics and incineration industries.
4. Other application areas include electrical insulators, kiln tools and catalyst carriers. Finely ground plate corundum powder is an excellent product for use as epoxy resin or resin system filler, and the desired high insulation strength, thermal conductivity and wear resistance can be obtained.
