White Alumina Oxide also called White Aluminum Oxide, White Fused Alumina, White Corundum.
White alumina oxide is made from industrial alumina powder, arc smelted at a high temperature of more than 2000 degrees, and then cooled. After crushing and forming, magnetic separation and iron removal, and screening into various sizes.
High-quality white alumina oxide depends on the quality of alumina powder, and the quality of alumina powder depends on the content of alumina and sodium chloride in it. When making white alumina oxide abrasives, the alumina content must be controlled above 98.4%. The content of sodium oxide is not higher than 0.6%, otherwise many substandard products will be produced, so the content of sodium oxide should be strictly controlled. High sodium oxide content will generate a lot of β-alumina, which will affect the properties of white alumina oxide, such as the decrease of crystal hardness of white alumina oxide, the decrease of cutting ability, easy pulverization and broken, low thermal stability and so on.
Special Alumina Oxide for wear resistant flooring, which have high hardness, acid and alkali resisting, corrosion resisting, wear-resisting, stable chemical properties and long service life.
Application:
ainly used in surface of out door flooing and pavement, such as deck of the ship or battleship, highway speed bumps, airport runway, etc.
Because of high acid and alkali resisting, corrosion resistance, wear resistance, it can also be used in indoor floors for special industry, for example, pharmaceutical industry, chemical industry, food process industry, etc.
