Tabular Alumina Refractory Material Manufacturer

Tabular alumina is a pure sintered α-alumina material that is completely densified by rapid sintering at temperatures over 1900 ° C without any sintering AIDS and is widely used in steel, casting, petrochemical, ceramics, incineration, and other industries. Alumina powder is an excellent filler in epoxy resin systems, with high dielectric strength, thermal conductivity, and wear resistance. It can be used in electrical insulators, kilns, catalyst support, and other fields.

Characteristics of tabular corundum

Tabular alumina refractory material has high hardness, high-temperature resistance, high compressive strength, excellent chemical stability, excellent optical properties, low thermal conductivity, and good electrical insulation.

Application of tabular corundum

1. Tabular corundum is widely used in refractory materials in the fields of steel, casting, the petrochemical industry, breathable bricks, ladle linings, castables, prefabricated parts, ceramics, and other fields. It is an excellent synthetic refractory material;
2. Platy corundum is an ideal refractory raw material. It can be used as aggregate in various aluminum refractory materials, and can also be added to other aluminum amorphous refractory materials;
3. Platy corundum is used as a sliding nozzle for pouring steel, crucibles, and utensils for smelting rare precious metals, special alloys, high metals, glass drawing, and making laser glass;
4. It is widely used in the furnace walls and roofs of various high-temperature furnaces. It is both high-temperature resistant and heat-insulating.

Tabular alumina factory transportation

When the plate corundum material is exported, it will first be packed in small bags, and then placed in large bags to facilitate transportation. The weight of each pouch can also be customized.
