Alumina, synthetically produced aluminum oxide, Al2O3, a white or nearly colourless crystalline substance that is used as a starting material for the smelting of aluminum metal. It also serves as the raw material for a broad range of advanced ceramic products and as an active agent in chemical processing
We are exporter of Calcined Alumina. According to different requirements, five series of products have been formed, including dry pressing, hot die casting, refractory, casting and setting, structural ceramic granulator, etc. It can be widely used in electronic equipment, structural ceramics, refractories, wear-resistant materials, polishing materials and other industries.
Grinding, blasting, and cutting processes, as well as the production of refractory materials, all employ alumina. We are proud to be the world's largest fused alumina producer and supplier. It is also known as fused aluminium oxide Alumina is found in the regions of Odisha, West Bengal, Kerala, Uttar Pradesh, Maharashtra and Tamil Nadu. There are several physical properties of alumina. It is high in hardness with the value of 9 on Mohs scale. It has sharp-edged grains, a high load bearing capacity, strong shock resistance, and thermal and chemical stability, besides their superior hardness. Alumina, or aluminium oxide (aluminum oxide), is better known in the mineral world as corundum with the chemical formula Al2O3 Alumina has widespread usage in several industries in refractories, sandblasting and abrasives to mention a few. Grinding, machining, blasting, cutting, and the manufacturing of shaped and unshaped refractory materials all employ fused aluminium oxide grits. We offer innovative, brilliant quality alumina mineral with both macro and micro sized that could be used for a wide range of applications. We can add refining procedures to our regular production of alumina mineral to suit the bespoke requirements of various industries and application domains. These various industries are ceramics, sand casting, tiles, enamels, laminates & paints, industrial coatings, abrasives, blasting, concrete & resin components, refractories, insulators and heat conductive to name a few.
What is Alumina? Alumina is a chemical compound that is formed of aluminum and oxygen with the formula Al2O3.It is called Aluminium Oxide. It has melting and boiling points of 2072 C and 2977 C, respectively. Aluminum Oxide has a density of 3.95 g/cm3. Why is Alumina powder used in ceramics? Although Alumina is an electrical insulator, it has a high heat transmission for a ceramic. Water does not melt Alumina. So, it is used in ceramics. What are the specifications of Alumina powder? Specifications of Aluminum Serial No Chemical Descriptions Percentage 1 Al2O3 99% 2 Fe2O3 0.05% 3 Mesh +200 How is alumina powder made for ceramics? Alumina are manufactured in ceramics from white particles or a smooth dense powder purified from bauxite. Alumina is a strong, long-wearing industrial ceramic which can only be produced via diamond cutting. What are the Uses in others? Alumina is a great element for bricks, plastics, polymers, and heavy clayware since it is chemically stable. It is also a popular component in sandpaper and a cost-effective alternative to industrial diamonds. What are the Side effects? Although Alumina is a beneficial metal, it is a skin irritant and it is also harmful for the environment. Itâ??s definitely uncomfortable in some cases
