Chemical Name: Magnesium Oxide
Chemical Formula: MgO
CAS No.: 1309-48-4
Appearance: White powder, odorless and tasteless
1. Extremely high melting point with excellent high temperature resistance and fire resistance
2. Slightly soluble in ethanol, hardly soluble in water, and readily soluble in acids
3. Possesses outstanding electrical insulation, thermal conductivity and moisture absorption capacity
4. Higher activity corresponds to stronger reactivity and adsorption capacity
1.A typical basic oxide capable of neutralizing acidic substances
2. Reacts slowly with water to produce magnesium hydroxide
3. Chemically stable with resistance to acid, alkali and corrosion
4. Maintains stable structure at high temperatures and is hard to decompose
1. The raw material is sourced from Qinghai hydromagnesite, with a guaranteed annual supply of 300,000 tonnes. Production output is stable, at approximately 150,000 tonnes per year.
2. The quality is comparable to that of Australian Queensland Magnesia (QMAG) grade and American Martin Marietta Magnesia grade.
3. Laboratory services: We have a dedicated nickel-cobalt laboratory and can provide experimental support for customers.
1. Used in nickel-cobalt ores, rare-earth ores, lateritic nickel ores, and cobalt precipitation in Congo copper-cobalt ores. Our product features high activity, fine particle size, and fast reaction. Its crystal structure is porous, increasing the specific surface area and enhancing reactivity. The cobalt precipitation rate reaches 38%.
2. Hydrometallurgical processing in mining operations. Magnesium oxide can replace sodium hydroxide at a 1:1.8 dosage ratio.
3. Wastewater treatment and seawater desalination (heavy metal removal).
4. Semiconductor industry circuit boards and precursors for lithium iron manganese phosphate battery materials.
