Coal mine : fire retardant uesd in cool mine.
Water treatment: magnesium chloride itself can quickly remove the impurities in the water , and it does not cause two pollution. it is especially suitable for the treatment of large soale polluted water safer.
Being the important inorganic raw material in chemical industry,it is used for producing magnesium compounds such as magnesium carbonic acid,magnesium hydroxide and magnesium oxide,etc..
In metallurgy industry it is used to produce metal magnesium,liquid chlorine and high-purity magnesia.
In the construction material industry it is the important raw material in the production of light construction materials,such asglass fabric tile,decoration board,sanitation waer,ceiling,floor brick and magnesium oxide cement,which are articles used for high-rise buildings.
In the magnesium carbonate articles it can be used to produce high-quality magnesiumtile,high-quality fireproofing board,magnesium packing box,magnesium decorationboard,light wallboard,milling ware,stove ware and the fireworks solid fusing agent,etc.
In other fields it is used in food additive,protein firming agent,thawagent,cryogen,dustproof agent and refractories,ect.
