The homogenizing material is formed by the raw materials of high alumina bauxite ore with loose structure and cannot be directly sintered, and is formed through the steps of batching, grinding, iron removal, filtration, molding, drying, and firing. The section is blue-black, with dense texture and regular grain development, most of which are above 15 μm. It has the characteristics of stable index, uniform composition, high bulk density, excellent high temperature performance, no need for grading and sorting when using, low comprehensive cost, and high cost performance. It can be used in place of brown corundum and other products.

1. Due to its high temperature resistance, corrosion resistance, high strength and other properties, it is used as a sliding nozzle for pouring steel, smelting rare and precious metals, special alloys, high-purity metals, glass drawing, crucibles and utensils for making laser glass; various high-temperature furnaces and kilns , such as refractory materials, ceramics, linings (walls and pipes) of iron-making blast furnaces; physical and chemical utensils, spark plugs, heat-resistant and anti-oxidative coatings. It is a special lining for carbon black, boron chemical industry, fertilizer, synthetic ammonia reactor and gasification furnace.

2. Due to the characteristics of high hardness, good wear resistance and high strength, it is used in chemical systems as various reaction vessels and pipelines, parts of chemical pumps; as mechanical parts, various molds, such as wire drawing dies, extruding pencils Mandrel mouth, etc.; for knives, abrasives, bulletproof materials, human joints, sealing grinding rings, etc.

3. Due to its high temperature insulation, it is used as a wire sleeve and protection tube for thermocouples. The insulation used in atomic reactors is still excellent. In addition, the loss is not large, and the dielectric constant is not large. It is widely used in the electronics industry. It is used for solid integrated electric furnace substrate socket, shell, porcelain frame, thin window, missile radar antenna protective cover, etc.
