[22] Aluminosilicate glass is a commonly used type of glass that often contains 5% to 10% alumina. All copyrights reserved on revision notes, images, It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond. In this video i will show the lewis structure for ionic compound for aluminum oxide al2o3. electrons in the aluminium ion. In terms of its crystallography, corundum adopts a trigonal Bravais lattice with a space group of R3c (number 167 in the International Tables).

In its most commonly occurring crystalline form, called corundum or α-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting tools.[7]. because there are two more negative electrons than there are positive Aluminium oxide, being a dielectric with relatively large band gap, is used as an insulating barrier in capacitors.[30]. It is commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. Metallic aluminium is very reactive with atmospheric oxygen, and a thin passivation layer of aluminium oxide (4 nm thickness) forms on any exposed aluminium surface in a matter of hundreds of picoseconds. [citation needed], In its finest powdered (white) form, called Diamantine, aluminium oxide is used as a superior polishing abrasive in watchmaking and clockmaking.
