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 is roughly 8.5 - 9.0 on the hardness scale.
No, only aluminum oxide, lead oxide and zinc oxide are amphoteric oxides.
Aluminum oxide, as corundum, defines 9.0 on the Mohs hardness scale.
Magnesium and oxygen combine to form magnesium oxide (MgO). Magnesium oxide is a white solid that occurs naturally as the mineral periclase. It is commonly used in various industrial applications, including as a refractory material and in the production of ceramics.
Assuming Oxygen is the oxidizing element: 2Mg + O2 -> 2MgO + energy So your answer is MgO or Magnesium oxide or Magnesia
Aluminum Oxide is roughly 8.5 - 9.0 on the hardness scale.
When aluminum burns, it reacts with oxygen in the air to form aluminum oxide, releasing heat and light. When magnesium burns, it also reacts with oxygen to form magnesium oxide and emits a bright white light.
Aluminum oxide is not considered metallic because it is a ceramic material. It is a compound formed between aluminum and oxygen, and it exhibits properties such as high hardness, electrical insulation, and thermal resistance.
No, aluminum does not react with magnesium oxide (MgO) under normal conditions. Both aluminum and magnesium oxide are stable compounds, and they do not undergo a chemical reaction when in contact with each other.
Magnesium Oxide
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.
No, only aluminum oxide, lead oxide and zinc oxide are amphoteric oxides.
Magnesium oxide is formed when magnesium metal reacts with oxygen. It is an oxide of magnesium. Magnesium is the metal, and magnesium oxide is the resulting compound formed when magnesium reacts with oxygen.
The pH of Magnesium oxide is 10.3, which is slightly alkaline.
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.

Zinc oxide reacts with metallic magnesium to produce magnesium oxide and metallic zinc.
