Products Description
Aluminium Oxide (Al₂O₃) Granules are white solid particles with the chemical formula Al₂O₃ and a molecular weight of 101.96 g/mol.
They have a high melting point (2072°C), a high boiling point (2977°C), and a high density (3.987 g/cm³). With a Mohs hardness of 9, they are second only to diamond in hardness.
This material is chemically stable, resistant to acids and bases, and almost insoluble in water. Due to these properties, it is an excellent ceramic material.
Aluminium Oxide (Al2O3) Granules have applications in numerous areas of life.Aluminium Oxide (Al2O3) Granules serve a major role in grinding and polishing, refractory and ceramic material production, and are also used as catalyst supports in electronic components and medical and dental instruments.The high hardness, heat resistance, chemical stability, and biocompatibility of Aluminium Oxide (Al2O3) Granules allows them to fulfill various industrials and medical needs.These properties enable Aluminium Oxide (Al2O3) Granules to be a crucial high performance material in many fields.
Alumina Powder features
High Hardness & Strength：Al₂O₃ performs exceptionally well in grinding and polishing applications already with a compressive strength around 2000MPa and Mohr's hardness of 9, dwarfed only by the diamond.
Excellent Thermal Stability：Its melting point reaches an astounding 2072°C allowing it to stabilize under great thermal stress, making it ideal for furnace linings and thermal insulation materials.
Chemical Inertness：Al₂O₃ excels in harsh chemical environments due to being highly resistant to most acids, alkalis and having near zero solubility in water.
Electrical Insulation：Al₂O₃ and is an excellent insulator for electric components and semiconductors due to its exceptional insulating properties and a dielectric strength of approximately 15kV/mm.
Biocompatibility：Widely used in medicine for hip and knee replacements, dental implants and bone grafts due to its non-toxic and reactive nature, making it an exceptional material for biocompatible devices.
