WebCrystal structure. The most common form of crystalline alumina, α-aluminium oxide, is known as corundum. Corundum has a trigonal Bravais lattice with a space group of R-3c (number 167 in the International Tables). The oxygen ions nearly form a hexagonal close-packed structure with aluminium ions filling two-thirds of the octahedral interstices. WebFeatures of Transparent Aluminum Transparent aluminum or ALON is a transparent polycrystalline ceramic with a cubic spinel crystal structure. Its chemical formula is Al 2 O 27 N 5. ALON is produced by combining aluminum, oxygen, and nitrogen.
