What is the alumina content of white corundum?
The main component of white corundum is alumina
The alumina α-Al2O3 in white corundum is precisely due to the content of alumina, so white corundum has high temperature resistance, wear resistance, hardness and other properties, so the level of alumina content is the most important indicator to measure the quality of white corundum , and what is the content of alumina related to? The alumina content mainly depends on the raw materials: the quality of alumina powder and the smelting time are related. Among them, “GBT 2479-2008 Ordinary Abrasive White Corundum” stipulates that the Al2O3 content should be above 99.0%.
