Aluminum oxide powder msds is used for its hardness and strength. The naturally occurring form is corundum, a mineral that is 9 on the Mohs scale of mineral hardness (just below diamond).
Aluminium oxide powder is used as an abrasive, and its high heat resistance makes it popular in grinding operations. It also serves as an abrasive in a variety of polishing applications, such as CD/DVD polishing and scratch-repair kits.
Alumina is a common component in the cue tip "chalk" used in billiards, and it is an ingredient in some toothpaste and dental filler. It is also an important ingredient in a number of cosmetics, including sun block and lipstick.
Chemically, aluminium oxide is a silicate with a spherical crystal structure. It can be obtained in several different forms.
The most common form is corundum, which adopts a trigonal Bravais lattice with space group R3c. This is a thermodynamically stable form that can be shaped by a variety of techniques, such as electrolytic oxidation.
It is a common component of alumina ceramics, used in a variety of industrial and consumer products. It is used in refractory materials, as a catalyst support for many industrial reactions and as a fire retardant/smoke suppressant in some types of glass.
A very low hazard for usual industrial handling, but may cause eye and skin irritation. Inhalation may lead to respiratory tract irritation and lung damage.
