What are the USES of alumina
The use of alumina, alumina mainly used in what aspects!The use of alumina, alumina mainly used in what aspects!Alumina is a white amorphous powder, commonly known as alumina, 3.9 4.0 g/cm3 density, melting point 2050 ℃, boiling point 2980 ℃, insoluble in water, alumina are alpha and gamma two variations, can be extracted from bauxite on industrial alumina product series now a lot of, for example: aluminum hydroxide high temperature alumina high purity alumina calcined alumina white aluminum hydroxide industrial-grade aluminium hydroxide toothpaste grade levels, hydrogen alumina agate, aluminum hydroxide filler aluminum hydroxide and so on.Alumina products are widely used in economic construction or life, it has its existence, it plays a unique role.Alumina special refractories are: fine refractory ceramic products light insulation products fiber products and unshaped products, and its main application range is:
(1) Lining structural materials for ultra-high temperature kilns.
(2) Heap pot for refining and purification of high purity metal superalloy rare metal.
(3) High temperature furnace tube thermocouple tube high temperature insulation.
(4) High temperature resistant kiln furniture gasket pressure bar and pressure block, etc.
(5) High temperature resistant and corrosion resistant lining materials for petrochemical industry.
(5) Transparent alumina ceramics can be used as high pressure sodium lamp tube microwave high temperature observation window glass.
(7) In the electronic industry to do circuit substrate valve seat high voltage ceramic shell radar antenna spark plug.
(8) Abrasives and abrasives, such as grinding wheel, cutting piece, wire drawing die, wire drawing tower wheel, textile porcelain pieces, abrasive nozzle, high temperature wear bearing and various props, etc.
(9) Chemical industry plunger pump components seal ring, etc.
(10) Molten metal conveying pipelines for metallurgical and non-ferrous industries.
(11) Various industrial sectors of high temperature and energy efficient materials such as alumina hollow ball alumina whisker alumina fiber and other products.
