USES :

1. Metallurgical industry: Used as the adhesive of manufacturing refractory materials and build by laying bricks or stones furnace arm , and is metal materials of making 2 fusing agent and smelting magnesium . 2. Chemical industry: mainly used for production of magnesium salt, such as magnesium oxide, magnesium hydroxide, magnesium carbonate, firecrackers solid lead agent, also used as raw materials of antifreeze . 3. Building materials: magnesium chloride and magnesium oxide (MgO magnesia diamond) made magnesia cement of hard corrosion resistance , which can be made into artificial marble, magnesia tile, floor, ceiling, decorative, fire prevention board, canopy support, partition board, magnesium the manhole covers, bath crock, door window frame, cooker, methane tank, magnesium the crafts and mobile home. 4. Machinery industry: In daily life, the current magnesia can be made into mechanical packing container, triangular pad edge and the furniture and so on, is good material "to the soil and material" . 5. The food industry: Tofu using brine (magnesium chloride aqueous solution) point system tastes fresh than that using stone point system. It also used as part of the food additive. 6. The traffic industry: used as road deicing snow melt agent, deicing speed, small corrosive to vehicles, more effective than sodium chloride.7. Medicine: magnesium chloride into "halide dry" for medicinal. 8. Agriculture: can be used to manufaceturing magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant.
