Appearance & basic properties: White fine powder, odorless, insoluble in water, soluble in acids. Melting point ~2800 °C; hygroscopic (absorbs moisture and CO₂ from air).
Grades by form: Light (bulky, reactive) and heavy (dense, compact).
Purity levels: Industrial (75–85 % MgO), food/pharma (strict standards), and high‑purity/nano (≥99.9 %).
Main uses: Refractories, acid neutralisation, magnesia cement, electrical insulation, filler in polymers, food antacid/additive, and advanced ceramics.
Exceptional thermal stability – With a melting point of ~2800 °C, MgO serves as an indispensable raw material for high‑temperature refractories, effectively extending furnace service life and reducing maintenance costs.
Mild alkalinity and strong neutralisation/adsorption – It efficiently treats acidic wastewater and flue gases, while also being safe for use in dietary supplements and food as an acidity regulator and magnesium supplement, meeting both environmental and health requirements.
Flexible production & customisable grades – By adjusting calcination temperature and processing, MgO can be produced in light, heavy, or nano forms, with purities ranging from Industrial (75–85 % MgO), food‑grade and dietary (strict standards), and high‑purity/nano (≥99.9 %).. This allows precise tailoring for applications such as magnesia cement, electrical insulation, silicon steel coatings, and electronic ceramics.
Reinforcing filler for polymers – As a cost‑effective additive, it simultaneously improves the strength, heat resistance, and flame retardancy of plastics, rubber, and coatings, offering excellent performance at a competitive price.
Chemical inertness & electrical insulation – Its stable chemical behaviour and high dielectric strength ensure long‑term reliability in demanding environments, making it suitable for electronic and electrical components.
Refractories – Fire bricks, crucibles, furnace linings (high‑temp resistance).
Environmental – Acid neutralisation, flue gas desulphurisation, heavy metal removal.
Construction – Magnesia cement (lightweight, fireproof, strong).
Electrical & Electronics – Insulation fillers, silicon steel coatings, ceramic substrates.
Food & Pharma – Food & Health Products – Anti‑caking agent, acidity regulator, antacid, magnesium supplement.
Advanced Materials – Nano‑MgO for catalysts, high‑performance ceramics, and microwave absorbers.
When handling magnesium oxide, always store it in a tightly sealed container in a cool, dry, well‑ventilated area, as it readily absorbs moisture and carbon dioxide from the air, which can cause caking and reduce its reactivity. Avoid contact with strong acids or acid‑forming substances, as vigorous neutralisation reactions can generate significant heat and potentially cause splashing. During processing, wear appropriate personal protective equipment (dust mask, safety goggles, and gloves) to prevent inhalation of fine powder, which may irritate the respiratory tract, eyes, and skin. In case of large‑scale use, ensure local exhaust ventilation to minimise airborne dust concentrations. While MgO is relatively non‑toxic, accidental ingestion should be treated by rinsing the mouth and seeking medical advice. Spills should be swept up gently (avoiding dust generation) and disposed of in accordance with local environmental regulations. Finally, never mix MgO with flammable materials near ignition sources, as its dust cloud can pose a fire or explosion hazard under extreme conditions.
