yes I don't know about in normal form (like powdered), but crystal aluminium oxide is know as a sapphire(or a ruby if it has red impurities). Sapphires and Rubies have a hardness of 9 on the Mohs scale (diamond is 10) they are the second hardest natural material.

Aluminum oxide, also known as alumina, is a chemical compound of aluminum and oxygen. Fused aluminum oxide or fused alumina is a synthetic abrasive material commonly used for sandblasting, grinding, and polishing due to its hardness and wear-resistant properties. This material is produced by melting aluminum oxide at high temperatures and then cooling it to form a crystalline structure suitable for various abrasive applications.

PH of magnesium oxide?

The pH of Magnesium oxide is 10.3, which is slightly alkaline.


Which is the least reactive sodium aluminum or magnesium?

Aluminum is the least reactive among sodium, aluminum, and magnesium. This is because aluminum is more stable due to the presence of a protective oxide layer on its surface, which prevents further reactions. Magnesium is more reactive than both sodium and aluminum.
