Magnesium oxide (MgO, CAS 1309‑48‑4) is a white, hygroscopic mineral powder produced by calcining magnesite. It has a molecular weight of 40.30, a melting point of 2852 °C, and a pH of 10.3 in saturated solution. It is widely used in refractories, electrical insulation, agriculture, water treatment, dietary supplements, and chemical processing.
| Property | Value |

| EINECS Number | 215-171-9 |
| Melting Point | 2800–2852 °C |
| Boiling Point | 3600 °C |
| Densit | 3.58 g/cm³(20 °C) |
| pH (Sat. Solution) | 10.3(20 °C) |
| Refractive Index | 1.736 |
High thermal stability – melts at 2852 °C, usable above 2000 °C.
Excellent electrical insulator – wide bandgap (7.8 eV), dielectric constant 9.6.
Buffered alkalinity – pH naturally capped at 10.3, avoids over‑alkalisation.
High Mg content – ~60% elemental magnesium, 3.75× more than citrate.
Two physical forms – light (fluffy) and heavy (dense) for different processing needs.
Non‑toxic & eco‑friendly – safe for food, feed, and pharmaceutical use.
Cost‑efficient – highest Mg content per gram reduces material costs significantly.
Superior heat resistance – withstands extreme temperatures with low thermal expansion.
Safe pH control – gradual neutralisation protects equipment and tissues.
Versatile – serves refractories, pharma, agriculture, insulation, and catalysis.
Regulatory ready – available in USP/FCC/EP grades with Kosher/Halal options.
Improved formulation – light grade gives excellent flowability; heavy grade reduces capsule size.
Refractories – linings for furnaces, kilns, crucibles.
Dietary supplements & healthcare – antacids, laxatives, tablet excipients (light grade).
Agriculture – soil pH correction, magnesium fertilizer, animal feed additive.
Water & wastewater – acid neutralisation, heavy metal precipitation, phosphate removal.
Electrical insulation – filler in mineral‑insulated cables and heating elements.
Construction – magnesium oxychloride cements, fireproof boards.
Catalysis & adsorption – catalyst support and CO₂ capture.
Production – calcination of magnesite or Mg(OH)₂ at 400–1000 °C (light grade) or >1000 °C (heavy grade).
Grades – purity from 85 % (industrial) to 99.99 % (high‑purity 4N); light (bulk density ≤0.15 g/mL) and heavy (≥0.25 g/mL).
Key parameters – MgO content, loss on ignition, particle size distribution, specific surface area, and acid‑neutralising capacity.
Standards – compliant with USP, FCC, EP, and other national pharmacopoeias where applicable.
Buffered alkalinity – MgO hydrolyses slowly in water to Mg(OH)₂, releasing OH⁻ ions but capping pH at ≈10.3, avoiding sudden over‑alkalisation.
Thermal resistance – ionic crystal structure with very high melting point (2852 °C) and low thermal expansion, providing exceptional heat endurance.
Adsorption & reactivity – porous surface (especially light grade) enables physical adsorption of impurities and chemical reaction with acidic species.
Cementitious reaction – reacts with MgCl₂ or MgSO₄ to form strong, fire‑resistant oxychloride/sulphate cements.
Technical support – formulation advice, processing optimisation, and application troubleshooting.
Sample service – free or small‑charge samples for qualification trials.
Documentation – full COA, SDS, and regulatory certificates (Kosher, Halal, GMP) provided.
Logistics – global shipping with proper handling and storage guidance.
After‑sales – quality feedback, continuous improvement, and dedicated account management.
