Corundum brief analysis of the composition and uses

Corundum based on industrial alumina powder as raw material in the arc by melting temperatures above 2000 degrees made. Corundum main chemical ingredient is AL2O3, the content of a 98.65% -99.37 % , and the other a small amount of Fe, Si, Ti and so on. Corundum behalf # "WA" on internationally accepted standards, national standards, most for export, there is a certain amount of supply domestic users . Prominent feature is the small crystal size impact resistance, due to a self- processing mill crushed particles are mostly spherical particles , dry surface cleaning, easy binding agent combination .
Corundum is high-quality aluminum oxide powder as raw material , through the fused corundum sand refining crystal, high purity, good self-sharpening , acid corrosion , high temperature, thermal properties and stability. Slightly higher than corundum corundum hardness , toughness slightly lower , high purity, good self-sharpening , grinding ability , heat a small , high efficiency, acid and alkali resistance , high temperature resistance and good thermal stability . Made with corundum abrasive sand , suitable for grinding high carbon steel , high speed steel and stainless steel fine-grained abrasive . Corundum of sand can also be used for precision casting and high-grade refractory .
