The magnesium carbonate is an important inorganic chemical product, and has extensive applications. Among the extensive applications, the major application is to be industrial center material. It can prepare high pure magnesium oxide.
As a kind of typical magnesium carbonate product, the magnesium carbonate whisker is the single crystal from magnesium carbonate hydrate, and has many advantages in impurity and strength. What’s more, it can be used for the filler of composite material, for example, used for the reinforce and modification of plastic, rubber, coating and ink. It can express excellent physical and chemical function, outstanding mechanics function. The magnesium carbonate whisker can be used as the centrebody to prepare high pure magnesium oxide and basic magnesium carbonate.
Becauses it is consisted of schistose crystallite, the basic magnesium carbonate has high specific surface area, high oil absorbency, high water-absorbing quality, low bulk density and porosity. Therefore, it can be used as paper wadding with low density. What’s more, the tubular basic magnesium carbonate also can be used as cavity carrier, and has slow release feature. the basic magnesium carbonate is light and loose. Therefore, it can be used as fireproof thermal insulation plate and fire-proof material which is adiabatic and heat resisting.
