What are the industrial uses of magnesium oxide?
1. Refractory Materials (High-Temperature Applications)
Steel Industry:Industrial magnesium oxide powder Lining furnaces, ladles, and kilns (can withstand temperatures >2000°C).
Cement & Glass Production:Industrial magnesium oxide powder Used in rotary kilns and glass melting furnaces.
Ceramics:Industrial magnesium oxide powder Acts as a stabilizer in high-temperature ceramic products.
2. Environmental Protection
Flue Gas Desulfurization (FGD): Neutralizes sulfur dioxide (SO₂) in coal-fired power plants.
Wastewater Treatment:
Industrial High Purity Magnesium Oxide Adjusts pH in acidic industrial wastewater.
Industrial High Purity Magnesium Oxide Removes heavy metals (e.g., Pb, Cd) by forming insoluble hydroxides.
Soil Remediation: Industrial High Purity Magnesium Oxide Stabilizes contaminated soils by immobilizing heavy metals.
3. Agriculture
Soil Amendment:Magnesium Oxide food Grade Corrects soil acidity (raises pH) and supplies magnesium, a vital nutrient for crops.
Animal Feed Additive:Magnesium Oxide food Grade Prevents magnesium deficiency in livestock.
4. Construction & Building Materials
Fireproofing: Added to wallboards, cables, and coatings for flame resistance.
Magnesium Cement (Sorel Cement): Light Magnesium Oxide Combines with MgCl₂ to form durable, fast-setting cement for flooring and panels.
Insulation: Light Magnesium Oxide boards used in energy-efficient buildings.
5. Chemical & Pharmaceutical Industries
Magnesium Oxide food Grade Precursor for Magnesium Compounds:
