Aluminum Oxide Crucibles (Al2O3) are ceramic crucibles made of Al2O3, used extensively in high-temperature processes for casting and melting metals due to its excellent durability, thermal resistance and chemical reaction resistance. Crucibles made of Aluminum Oxide have become popular due to their toughness as well as high melting point. Crucibles made from Al2O3 also resist thermal shock making them well suited for research facilities as well as industrial settings with high temperatures or harsh environments requiring them.
