Alumíniumoxidból
Alumíniumoxidból is the Hungarian word for "from aluminum oxide." Aluminum oxide, also known as alumina, is a chemical compound with the formula Al2O3. It is an amphoteric oxide, meaning it can react with both acids and bases. Naturally occurring aluminum oxide is rare, with the mineral corundum being a common example. Corundum is known for its hardness and is used as an abrasive and gemstone, with ruby and sapphire being varieties of corundum colored by impurities.
In its pure form, aluminum oxide is a white, crystalline solid. It is highly insoluble in water
Aluminum oxide is produced industrially through the Bayer process, which involves the purification of bauxite ore.
