Applications

Aluminum oxide finds use as catalyst in organic synthesis and chromatography. It is used as an ingredient in sunscreen lotions and paints. It is also used in the manufacture of abrasives, refractories, ceramics, filler for plastics, dosimeter, spark plug insulators, and electrical insulators. Aluminum oxide is used widely to produce aluminum metal.

Notes

Predominantly γ phase, 5-20% α phaseAluminium oxide is an amphoteric substance
