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.
Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.
