The domestic annual output of magnesium oxide is about 12 million tons.

 Determination of sulfur in coal and pyrite and sulfur and arsenic in steel. Used as a standard for white pigments. Light magnesia is mainly used as a raw material for the preparation of ceramic activated magnesia, enamel, refractory crucibles and refractory bricks. Also used as polisher binder url] paint] and filler for paper, accelerator and activator for neoprene and fluororubber. After mixing with solutions such as magnesium chloride, it can be made into magnesium oxide water. It is used as an antacid and laxative in medicine, for hyperacidity, gastric and duodenal ulcer disease. In the chemical industry, it is used as a catalyst and a raw material for the manufacture of magnesium salts. It is also used in the manufacture of glass, dyed meal, phenolic plastics, etc. Heavy magnesia is used in the rice milling industry for firing mills and semi-drums. The construction industry is used to make artificial chemical floors, artificial marble, heat protection panels, sound insulation panels, and plastic industry as fillers. It can also be used to produce other magnesium salts.

 For rubber, plastic, wire, cable dyes, paint, glass, ceramics, chemical reagents, medicine, food additives, etc.

 Join Light Burning Powder

 Used in libraries to prevent books from being corroded by acid;

 Insulation for wires;

 For the treatment of heartburn, acid and acid indigestion;

 Used as a short-acting laxative;

 as a magnesium supplement;

 Because it is refractory, it can be used as furnace lining;

 Used as a reference for white in colorimetry; (emissivity is about 0.9)

 Finely divided magnesium oxide can be used as an optical coating. When the coating thickness is between 300 nanometers and 7 mm, the coating is transparent. A 1 mm thick coating has an index of refraction of 1.72.

 For rock climbing purposes, it can absorb sweat from hands. Note: Inhalation of magnesia fumes can cause metal fume sickness.

 Mainly used to formulate oral medicines to neutralize excess stomach acid. Commonly used preparations are: milk of magnesia--emulsion; magnesium cover sheet--each tablet containing MgO 0.1g,; acid-making powder--a powder made by mixing magnesium oxide and sodium bicarbonate, etc.

 The content and activity of magnesium oxide are proportional within a range and inversely proportional beyond this range!

 Magnesium oxide is now misunderstood by most people as light-burning powder. In fact, this understanding is wrong. Light-burning powder can be said to be a kind of magnesium oxide. Its alias is also called light-burning magnesium oxide, light-burning magnesium oxide. Magnesium bitter soil, bitter soil powder (transliteration in Japanese), magnesium calcium powder (because the light burning powder contains calcium oxide) The lower the calcium oxide content in the light burning powder in the building materials industry, the better!

 Properties: White light powder, odorless, exposed to air, easy to absorb water and carbon dioxide, this product is soluble in acid and ammonium salt, insoluble in water and ethanol, melting point 2800, boiling point 3600, magnesium oxide has high fire resistance and insulating properties, melting point very high.
