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, ปิโตรเคมี, เซรามิกส์, incineration, และอุตสาหกรรมอื่นๆ. Alumina powder is an excellent filler in epoxy resin systems, with high dielectric strength, การนำความร้อน, and wear resistance. It can be used in electrical insulators, เตาเผา, catalyst support, และสาขาอื่นๆ.

Characteristics of tabular corundum

Tabular alumina refractory material has high hardness, ทนต่ออุณหภูมิสูง, high compressive strength, excellent chemical stability, excellent optical properties, การนำความร้อนต่ำ, 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, หล่อได้, prefabricated parts, เซรามิกส์, และสาขาอื่นๆ. 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, เบ้าหลอม, 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.
