Introduction to Alumina:
Alumina (Aluminum Oxide – Al2O3) is one of the most widely used ceramic compounds and a key raw material in the metallurgy and refractory industries. It appears as a white powder with outstanding physical and chemical properties, making it suitable for a broad range of industrial uses.
Due to its high melting point, hardness, chemical stability, and excellent thermal and electrical insulation, alumina is essential in the production of refractory bricks, advanced ceramics, abrasives, and catalytic supports. It also plays a vital role in the production of aluminum metal from bauxite.
Rayka Tejarat Diba supplies high-purity industrial and laboratory-grade alumina in customized packaging, with guaranteed quality and certified analysis suitable for advanced manufacturing.
