How to distinguish the quality of Henan white corundum?
1. White corundum is a white artificial corundum made of alumina powder through a series of processes. The main component is AL2O3. It has the characteristics of moderate hardness, good self-sharpening, wear resistance and stable chemical properties. Suitable for abrasives, industrial chemicals and refractory materials.
2. The higher the alumina content in white corundum, the better the purity and quality of the white corundum. When choosing white corundum, look at the purity of white corundum. If the purity is not good, it means that the quality of white corundum is not necessarily good.
3. The hardness of white corundum can also show the quality of white corundum. The hardness of white corundum is larger, which is slightly better than that of brown corundum. Therefore, careful observation of the hardness of white corundum can also distinguish the quality of white corundum.
