Commonly Used In Steel Smelting Casting Furnace Lining Flame Equipment Magnesium Oxide (MgO)
Product Description
Magnesium oxide (MgO, CAS: 1309-48-4) is a high-performance inorganic alkaline powder produced by high-temperature calcination and purification of magnesium-based raw materials. It features stable chemical properties, excellent thermal stability and superior electrical insulation.
Available in industrial, food, pharmacy and active grades as well as light and heavy types, MgO is widely used in refractories, rubber additives, chemical industry, food fortification, pharmacy, environmental protection and electrical insulation fields. With low impurities and strong environmental adaptability, it serves as an essential core auxiliary material for modern industrial and fine chemical production.

Process Flow
Step
Process
Description
1
Raw Material Selection
High-purity magnesium carbonate or magnesium ore selected as the primary raw material
2
Calcination
Heated in a high-temperature furnace (approx. 800–1000°C) to produce MgO via thermal decomposition
3
Cooling & Crushing
Material cooled and ground into fine powder to achieve the desired particle size
4
Purification & Screening
Impurities removed through purification, then screened to meet required particle size and purity
5
Quality Testing
Subjected to strict QC tests: particle size distribution, purity, moisture content, and other physical properties
6
Packaging
Packed in moisture-resistant, airtight containers to preserve quality
Technical
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.
Service
Customisation – particle size, bulk density, purity level, and packaging (bags, big bags, drums) tailored to client needs.
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.
