• 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.

• Superior Raw‑Material Base: Manufactured from carefully‑selected high‑grade magnesite ore for premium product quality.
• Dependable Field Performance: Delivers stable outcomes even within harsh and demanding industrial operating conditions.
• Cost‑Eco Balanced Production: Adopts cost‑effective manufacturing workflows with environmentally‑friendly processing standards.
• Extended Shelf Life: Features low moisture absorption, effectively prolonging storage duration.
• Broad Process Compatibility: Shows high flexibility and good adaptability to a wide array of industrial processes.

• 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.

The direct‑method production relies on high‑temperature calcination of natural magnesite ore. Under intense thermal conditions, the raw ore decomposes thermally and releases carbon dioxide, yielding magnesium oxide as the final product. This carefully controlled manufacturing route delivers outstanding reactivity, low impurity levels, and uniform particle‑size distribution across batches.

Reaction Equation: MgCO₃ → Heat MgO + CO₂

• Buffered alkalinity – MgO hydrolyses slowly to Mg(OH)₂, releasing OH⁻ but capping pH at ≈10.3.

• Thermal resistance – ionic crystal structure with very high melting point and low expansion.

• Adsorption – porous surface (especially light grade) enables physical adsorption and chemical reaction with acids.

• Cementitious reaction – reacts with MgCl₂ or MgSO₄ to form strong, fire‑resistant cements.

• Customisation – particle size, bulk density, purity, packaging (bags, big bags, drums).

• Technical support – formulation advice, processing optimisation, troubleshooting.

• Sample service – free or charged samples for qualification.

• Documentation – full COA, SDS, and regulatory certificates (Kosher, Halal, GMP) provided.

• Logistics – global shipping with proper handling guidance.

• After‑sales – quality feedback and dedicated account management.

• Packaging: 25kg or 50kg woven bags with inner liners. Jumbo bags (500kg/1000kg) available for bulk orders.
• Storage: Store in a cool, dry place away from moisture and acidic substances. Avoid prolonged exposure to air to maintain product reactivity.
• Shelf Life: 12 months under recommended storage conditions.

• Avoid inhalation of magnesium oxide dust. Use proper personal protective equipment (PPE) such as masks and gloves.
• Handle with care to prevent the formation of airborne dust particles.
• Prevent contact with eyes or prolonged skin exposure; rinse thoroughly with water in case of contact.
• Keep away from acids and strong oxidizing agents to avoid hazardous reactions.
• Ensure adequate ventilation when handling large quantities.
