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.
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.
