Abstract: Industrial magnesium compounds,including five series products,such as magnesium oxide,magnesium hydroxide,magnesium chloride,magnesium sulphate and magnesium carbonate and other magnesium compounds have extensive uses in national economy.To satisfy the demand of internal and external markets,now it is necessary to keep focus on developing special magnesium oxides(e.g.active magnesium oxide,electric grade magnesium oxide,and silicon-steel grade magnesium oxide etc.),fireproofing magnesium hydroxide,and functional magnesium compounds (e.g.whisker,high-purity and nano-sized magnesium compounds) and on improving the quality of magnesium compound products.Some suggestions on the development of magnesium compounds were put forward,for example,to build ten-thousand level plant,to realize scale production,to generalize the patent technique of pyrogenation in low temperature,preparation technique of magnesium hydroxide by lime-brine method,and film separation technique
