Tabular Corundum

Plate corundum is named for its crystal structure of sheet a-A1203, which is formed by sintering of industrial aluminum oxide powder at 1800℃-1900℃, which is different from the process of fused corundum. Plate corundum is shrinkableThe bottom sintered corundum crystal has low impurity content, small porosity, low refiring shrinkage rate, good thermal shock stability, high temperature corrosion resistance, and good creep resistance.

Apparent porosity :≤0.3(%)

Volume density :≥ 3.5g /cm³

Application: Can be widely used in steel, casting, ceramics and other industries.

Plate corundum can be used as the main component in aluminum carbon, aluminum magnesium carbon, magnesium aluminum carbon, magnesium spinel, aluminum chromium refractory brick, and can also be introduced into high aluminum castable as a rich alumina component

Plate corundum has the general performance advantages of fused corundum, and less impurities, stable raw material quality, mature process, plate corundum has more advantages in all aspects of performance, quality is more reliable. Plate corundum can be used in iron and steel metallurgy, casting, glass, ceramics, chemical industry, electronics and other fields, as a senior refractory material.

In refractory materials, plate corundum is mainly used in steel and iron industry castable and refractory high aluminum brick, often used in various industrial kiln lining, ladle castable, sliding port castable, high aluminum 1 brick of iron mixing car, hot blast furnace exchanger, etc., with high temperature chemical corrosion resistance, thermal shock resistance, outstanding wear resistance, good thermal conductivity outstanding advantages.

① Do not add reducing agent, there will be no other substances in the process to pollute the product.

② High temperature resistance, the use temperature can reach 1800℃, is an excellent ultra-high temperature refractory material.

③ Good hardness and wear resistance, Mohs hardness 9.0, can be used as a refractory with high wear resistance requirements.

④ Good thermal shock stability and high temperature creep resistance, can be widely used as refractory castable or refractory brick.

⑤ plate corundum has good development, complete shrinkage and low water absorption;Good corrosion resistance, also shows excellent thermochemical stability at high temperature, resistance to hot metal, molten steel corrosion;The raw material is stable, the process is easy to control, and the product quality is stable.

① The main components of plate corundum and white corundum are a-AI203 crystal structure, plate corundum has lower impurity content and better developed crystal structure, and the performance is better than white corundum in all aspects.

②The main difference between plate corundum and white corundum is the process. Plate corundum is made of high temperature sintering, while white corundum is formed by melting, cooling and crystallization in electric furnace.

③ the sintering process of plate corundum has lower energy consumption and less pollutant emissions; And frit process white corundum high energy consumption, but also will emit a lot of polluting gases.
