Black corundum product properties
Black corundum, also known as low alumina corundum, is in the arc furnace, the bauxite smelting and made of a kind of α-Al2O3 and iron spinel as the main mineral phase of the gray black crystal, which is characterized by low Al2O3 content, and a certain amount of Fe2O3 (10% or so), so it has mode...Read more -
History of chrome corundum development
In 1877, Fremi, a French chemist, used pure alumina powder, potassium carbonate, barium fluoride and a small amount of potassium bichromate as raw materials. After 8 days of high temperature melting in a crucible, small ruby crystals were obtained, which was the beginning of artificial ruby. In 1...Read more -
Chromic corundum
Chrome corundum: The main mineral composition is α-Al2O3-Cr2O3 solid solution. The secondary mineral composition is a small amount of compound spinel (or no compound spinel), and the content of chromium oxide is 1% ~ 30%. There are two kinds of fused cast chrome corundum brick and sintered chrome...Read more -
