🔑 Key Concepts & Definitions

• Al2O3 (Corundum): A crystalline form of aluminum oxide, known for its hardness of 9 on the Mohs scale, used as an abrasive material in grinding and polishing (source content).
• Na3[AlF6] (Cryolite): A mineral used as a flux in aluminum electrolysis, facilitating the reduction of aluminum oxide to aluminum metal (source content).
• MgAl2O4 (Spinel): A magnesium aluminum oxide mineral used in jewelry due to its attractive appearance and durability (source content).
• Al(OH)3 (Aluminum hydroxide): Used in antacids and as a fire retardant in plastics; also employed in medicine to treat indigestion and diarrhea (source content).
• AlCl3 (Aluminum chloride): Acts as a catalyst in organic chemistry reactions, especially in the production of various chemicals (source content).
• Be3Al2Si6O18 (Beryl): A mineral that includes emerald and aquamarine gemstones; also utilized in aerospace and electrical industries (source content).
