Product Description

Calcined Alpha Alumina (Calcined a-Al2O3) is a white powder with uniform particle size.Using high quality raw materials, calcined alumina is being produced in the rotary kiln on the reasonable temperature, with the characteristic of high conversion rate, stable crystallization and low impurity content.

Product Features

 
Calcined a-Al2O3 Calcined alpha alumina have excellent performance of high mechanical strength, stable shrinking rate, good electrical insulation, high wear resistance, and outstanding corrosion resistance, stable chemical properties, moderate shrinkage at high temperature, and good sintering performance.

Product Application

Calcined Alpha Alumina Application Because calcined alpha aluminahas high melting point,high hardness, stable crystal form, its products have high mechanical strength, good electrical insulation performance, corrosion resistance and fire resistance, so its application field is very wide. Usage: the main raw material for the high quality refractory products,castable application as well as fine ceramics and fine/ultra-fine polishing products. In the field of chemical industry, anti-corrosion coatings and catalyst carriers In the electronics industry, electronic substrates and insulation materials Constructing high-temperature furnaces and refractory structures in the field of refractory materials In the aerospace industry, manufacturing optical lenses and window materials
