Factory Supply: High-Quality Magnesium Oxide (Customizable Upon Request) — CAS No. 1309-48-4

Magnesium oxide (MgO)—also known as magnesia—is a white, odorless, and non-toxic powder that is insoluble in water and alcohol. It possesses high thermal conductivity and high mechanical strength. It is a white, hygroscopic solid mineral that occurs naturally as periclase and serves as a source of magnesium. Pure MgO is non-conductive and exhibits very high electrical resistance at room temperature. It features a high melting point (2852°C), high hardness (Mohs 5.5), and excellent electrical insulation and refractory properties. As a vital inorganic chemical raw material, it is widely utilized across industries such as rubber, pharmaceuticals, ceramics, construction, animal feed, and metallurgical refractories; it serves as a key raw material for high-temperature insulation, corrosion protection, flame retardancy, and mineral additives.

• Magnesium oxide is highly versatile and finds extensive application in fields such as construction materials, municipal management, agriculture, and machinery.
• In the construction materials industry, magnesium oxide is used to produce magnesium cement. This innovative type of cement offers numerous advantages, including light weight, high strength, thermal insulation, fire resistance, environmental friendliness, and energy efficiency.
• Fire Resistance: As a construction material, magnesium oxide wallboards possess a host of superior properties, such as resistance to fire, termites, moisture, and mold, as well as high structural strength. Due to its acid-buffering capacity and its efficacy in stabilizing dissolved heavy metals, magnesium oxide is widely utilized in industries involving soil and groundwater remediation, wastewater treatment, drinking water purification, air emissions control, and waste management.
• It also serves as a raw material for the manufacture of ceramics, enamel, refractory bricks, and similar products.
• In the chemical industry, magnesium oxide acts as a raw material for the production of magnesium sulfate, magnesium hydroxide, magnesium chloride, and other compounds.
• In the food industry, magnesium oxide is employed as a decolorizing agent for refined sugar, a pH regulator for ice cream mixes, and an anti-caking agent and antacid in various food products—including wheat flour, powdered milk, chocolate, cocoa powder, dextrose powder, and powdered sugar.
• In the medical field, magnesium oxide is used as an antacid, a magnesium supplement, and a short-term laxative to alleviate heartburn and indigestion; it is also utilized to ameliorate the symptoms associated with digestive disorders.

It is typically packaged in specifications such as 20 kg bags or 50 kg/jumbo. It should be stored in a dry, well-ventilated warehouse, protected from moisture and deliquescence, and kept away from acidic substances.
