The most abundant metallic element in the crust, with a content of 8.3%. Mainly present in aluminosilicate ores, as well as bauxite and cryolite. Aluminum oxide is a white amorphous powder that comes in various variants, among which the most familiar is α－ Al ₂ O Å and β－ Al ₂ O Å. Corundum, which exists in nature, belongs to α Al ₂ O Å, second only to diamond in hardness, has a high melting point and is resistant to acid and alkali. It is commonly used to make some bearings, abrasives, and refractory materials. Like a corundum crucible, it can withstand high temperatures of 1800 ℃. Al ₂ O Å comes in various colors due to the presence of different impurities. For example, those containing trace amounts of Cr (III) in red are called rubies; Sapphires contain Fe (II), Fe (III), or Ti (IV).

Aluminum is a light metal with the chemical symbol Al and atomic number 13. Aluminum is the most abundant metal element in the Earth's crust, ranking third in content after oxygen and silicon, and its reserves rank second among metals. Among the metal varieties, it is the second largest category of metals, second only to steel.
