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 2852 ℃, while boiling point is 3600 ℃.
Dissolved in acid and ammonium salt, but difficult to dissolve in water and
ethanol. When calcinations temperature reaches 400 ℃, its specific surface area
is 180 m2 / g.. When calcinations temperature reaches 1300 ℃, its
specific surface area is only 3 m2 / g.. It is easily deliquescence
in the air. It is a kind of binding cementing material.
