Alumina Tiles
Bulk density(g/cm3) ： ≥3.6 3.65 3.7 4.1 5.9
Advantage: 1.It has obvious advantages such as high hardness, good wear resistance, strong impact resistance, light weight and good stability.
2.Simple installation, low cost, and saving maintenance time.
Application:Coal conveying, material conveying system, pulverizing system ash discharge, dust removal system and other mechanical equipment with large wear in thermal power, steel, smelting, machinery, coal, mining, chemical, cement, port and wharf enterprises.
Details
Alumina Tiles are called special ceramics because of their high alumina content, relatively compact structure, and special properties. Al2O3 ceramic material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions are filled in two-thirds of the octahedral gaps. This is the same stable α-Al2O3 structure as natural corundum, so the ceramic has a high melting point and high hardness. , has excellent wear resistance.
The hardness of the ceramic tiles is ≥ HRA85, second only to the hardness of diamond, and the surface is smooth, the friction coefficient is small, and the wear resistance is very ideal, especially in the high temperature oxidizing medium or corrosive medium, the material of the alumina tiles has better performance than other metal materials. far superior.

Application
Wear-resistant alumina tiles can be directly lined in metal pipes, and are famous for their high cost performance, high hardness, good wear resistance, high temperature oxidation resistance, good corrosion resistance, powder erosion resistance, particle impact resistance and high temperature resistance. Alumina ceramic tiles widely used in thermal power, thermal power, steel, heat, cement, smelting, mining, chemical, machinery, paper, aluminum and other industries with severe wear and tear.
