Uses:

1 Metallurgical industry : adhesives used in the manufacture of refractories and stove arm and manufacturing II flux and smelting magnesium metal materials.

 

2 Chemical industry: mainly used for the production of magnesium salts , such as magnesium oxide , magnesium hydroxide, magnesium carbonate , firecrackers solid lead , disinfectants , chilled brine , and used to fill the fabric , paper , raw material is used as an antifreeze .

 

3 Building materials : magnesium chloride and magnesium oxide ( magnesia MgO) made of hard corrosion-resistant magnesia cement , can be made of artificial marble, dolomite tile , floors, ceilings, decorative panels, fire panels, ventilation ducts , greenhouses bracket, wall panels, Magnesite covers , bath , door frames , solar cookers , biogas digesters, ceramics, duck coop rubbit hutch , sheep hutch, pig barn , granary , abrasive, stoves, table tennis, magnesium wind pipe , cable tray , light rail pillow, flower, magnesite and other crafts and active board. 4 Machinery Industry : daily life, magnesite can be made with mechanical packing , triangular prism and furniture pads , is to " feed the soil on behalf of " the good stuff .

 

5 Transport sector : for road deicing salt and ice , and ice fast, small vehicles corrosive effects and antifreeze higher than sodium chloride . 

 

6 Agriculture : used as the magnesium fertilizer, potassium and magnesium fertilizer and cotton defoliant .

 

7 Fire : fire retardant material used in the production . Timber with brine , soaking the plate ( heat, pressure ) , the timber can be significantly improved flame resistance . And reduce wood smoke . Also for the production of fireproof material filler.
