Features:Alumina chemical formula Al2O3 is the main component of bauxite. White powder with different crystal forms, commonly known as α-Al2O3 and γ-Al2O3;α-Al2O3 is a hexagonal closely packed crystal, commonly known as corundum, with a melting point of 2045 ℃, a density of 3.965g/cm3, a 8.8 hardness, and is insoluble in water, acid or alkali. γ-Al2O3 is a cubic closely packed crystal, insoluble in water, but soluble in acid and alkali, and is a typical amphoteric oxide.
Use:Used for lithium battery diaphragm coating and electrode materials, precision polishing materials, alumina ceramic substrates, high-purity alumina grinding balls, toughening agents for zirconia grinding balls, electronic packaging materials, raw materials for the production of aluminum nitride by carbon reduction method, thermal engineering Plastic fillers, refractory materials, automobile spark plugs, inorganic membranes, bioceramics and other functional ceramics and structural ceramic materials.
Packaging:Composite paper bag, lined with plastic film bag, net weight 25 Kg/bag.
Storage:Sealed and stored in a cool, dry place to prevent moisture.
Chemson Industrial (Shanghai) Co., Ltd. was established in 1998. The main production of rubber chemicals, high-purity ultra-fine alumina and aluminum isopropoxide, aluminum sec-butoxide and other intermediate products.
