Application

Light magnesium oxide is used in ceramics, enamel, refractory crucible, refractory bricks, etc., also used as polishing agent, binder, paint and paper filler, neoprene accelerator, activator. In medicine, it can be used as antacids, laxatives, for the treatment of hyperacidity and duodenal ulcer disease, but also for glass, phenolic, plastics and other industries.

Dead-roasted magnesium oxide, namely magnesite, has granular type and brick type, being widely used as the refractory materials of steel furnace, cement kiln and glass furnace.

Alkaline granular refractory, mainly used for metal refining industry, with massive refractory for the furnace, or granular material for maintenance; Use spray, coating method to have it attached to the furnace wall in order to enhance the furnace fire resistance.

Magnesium oxide produce a positive charge inside the water with most of the suspended material being negatively charged, acting absorption role, can improve the filtration effect.manufacture of refractory crucibles, fire bricks, magnesia cements and boiler scale compounds, "powdered" oils, casein glue. Reflector in optical instruments; white color standard. Insulator at low temp.Magnesium oxide is used as an alkaline diluent in solid-dosage
forms to modify the pH of tablets.It can be added to solid-dosage
forms to bind excess water and keep the granulation dry. In
combination with silica, magnesium oxide can be used as an auxiliary glidant. It is also used as a food additive and as an
antacid, either alone or in conjunction with aluminum hydroxide.
Magnesium oxide is additionally used as an osmotic laxative and a
magnesium supplement to treat deficiency states.

Storage

Magnesium oxide is stable at normal temperatures and pressures.
However, it forms magnesium hydroxide in the presence of water.
Magnesium oxide is hygroscopic and rapidly absorbs water and
carbon dioxide on exposure to the air, the light form more readily
than the heavy form.
The bulk material should be stored in an airtight container in a
cool, dry place.Storage temperature: no restrictions.
