Caustic Calcined Magnesite Powder(Magnesium Oxide) is anti-bending,
anti-compression, highly-intensive, binding and cementing. It is widely used in
defense, medicine, chemical industry, papermaking, shipbuilding industries and
so on. In building industry, it could be used for tire-board, particle board,
insulation columns, railing, artificial marble, the inhalation of asbestos,
common tile, wall panels and ground laying.
With the advancement of
science and technology, the usage of light burning magnesium block is wider. It
could also be used to make civil products, packaging carton for light and heavy
machinery, packaging end beam, high temperature refractory materials, and
beautiful attractive bright glossing furniture. In machinery, it is also used to
cast models.
Magnesium oxide (MgO) is generally known as magnesite, light
burning powder, as well as magnesium oxide powder. Its density is 2.94, a kind
of white powder. Its melting point is 2852oC, while boiling point is
3600oC. Dissolved in acid and ammonium salt, but difficult to
dissolve in water and ethanol. When calcinations temperature reaches
400oC, its specific surface area is 180m2/g. When
calcinations temperature reaches 1300oC, its specific surface area is
only 3m2/g. It is easily deliquescence in the air. It is a kind of
binding cementing material. |
