3.Properties:
white or light yellow powder, odourless and tasteless, this product insoluble in water and ethanol,
melting point 2852 celcius degree,
boiling point, magnesium oxide are highly celcius degree 3,600 refractory insulation performance.
After 1000 celcius degree high temperature burning can change more than 1500 celcius
degree for crystal,
to burn into death is above magnesium or sintered magnesia.
4.Uses:
1) Used in rubber, plastic, wire and cable dye, paint, glass, ceramics, chemical reagent,
medicine, food additive, etc.
2)Used to prevent books in the library were acid corrosion; Used for wire insulation skin;
3)Used in the treatment of heartburn and stomach acid and acid indigestion; Used for short-acting laxative;
4)Used for magnesium supplementation; Because of the refractory, used for furnace lining;
5)In the colorimetric method for white frame of reference;
(emission rate at about 0.9) pressure thin magnesium oxide ,used for optical coatings.
6)In acid scattered - magnesia and sodium bicarbonate mixes powder,
one of the main purposes magnesium as flame retardant using
traditional retardant materials, magnesium oxide, another purpose is can be used as neutralizer,
magnesia alkaline,adsorption performance is good, can be used to make including acid waste gas,
waste water treatment,
organic wastewater treatment containing heavy metals and the neutralizer etc.
