Al2O3 (Alumina)

Aluminum oxide, or Al₂O₃, commonly known as alumina, is a stable, hard, and durable ceramic material derived from aluminum. It appears as a white or colorless powder and is used in various industrial applications, such as making refractory linings for high-temperature furnaces, cutting tools, and electronic substrates. Alumina is valued for its thermal resistance, electrical insulating properties, and wear resistance. It is also found in certain types of abrasives and in medical implants like joint replacements. Its combination of toughness and stability makes it a versatile material in both manufacturing and technological uses.
