The physical and chemical properties: Yuanjiang Brand - light magnesium oxide is a white amorphous powder. Odourless, tasteless, ruling. Relative density is about 3.58 (25 degrees). The melting point of 2852 degrees, the boiling point of 3600 degrees, poorly soluble in water, insoluble in alcohol, soluble in acid or ammonium salt solution. The above 1000 degrees high temperature burning, can be converted into crystal. When the temperature rises to more than 1500 degrees into dead burned magnesia and sintered magnesia. Absorb carbon dioxide from the air to generate basic magnesium carbonate.
Purpose: Yuanjiang Brand - light magnesium oxide Mainly used in the manufacture of ceramic, enamel, brick, etc., used as a polishing agent, adhesive, paint and paper packing, neoprene and fluorine rubber accelerator and activator, medicine, used as antacids and aperient, also used in glass, dye, plastic and other industries. The food grade used for the sugar delicate decoloring agent, toner, regulator, etc.
