company news about The method of making the magnesia refractory products

To produce high purity magnesium oxide raw materials, shall deliver the raw materials for chemical treatment.Usually it soluble in acid or water, cleaning solution, then the precipitation of magnesium hydroxide and alkali carbonate and so on, finally through heat decomposition can get pure magnesium oxide materials.
The high purity magnesium oxide after fused colorless transparent crystal can be obtained from electric smelting, it is also one of method to product magnesium oxide.
The sintering ability of pure magnesium oxide is determined by its manufacturing method, presintering temperature, the existence of impurities and added content, etc.
Prefabricated high purity and high density of magnesia products, the best is its raw material is magnesium hydroxide.In the manufacturing process, whatever the source of the magnesium oxide of magnesium hydroxide flame retardant materials can be made in advance, and then the presintering for easy sintered magnesia material.
Also has a magnesium oxide with alcohol and mineral oil press block, after mixing and burning.Presintering after grinding fineness to need.
Regardless of presintering temperature, MgO can be dissolved in acid, so, cannot use steel ball grinding and treated with acid, can use just the jade ball grinding mill lining and the quality of the jade research body.
Magnesia products and production process of alumina products are similar, but in the process to prevent the hydration and hydration degree of control.
Magnesia products according to their chemical properties is a typical basic refractory material.
