Magnesium Oxide
Industrial Grade Magnesium Oxide
General-purpose MgO where the application does not see trace CaO, chloride or iron. Used for neutralisation, pH control and general industrial processing.

MgO is a mild alkali. That mildness is the point: it neutralises acid without the handling hazard of caustic soda and without the secondary pollution that comes from over-dosing a stronger base.
What goes wrong in this industry
Caustic soda overshoots pH and the discharge fails on the way back down.
Lime sludge is slow and expensive to dewater.
Limestone desulfurisation produces a waste stream with no value.
Why Water & Flue-Gas Treatment
01Raises pH controllably and precipitates heavy metals as hydroxides at the pH you need.
02Leaves a sludge that dewaters more easily than lime sludge.
03Because the neutralisation is mild, overshoot — and the secondary pollution that follows it — is much harder to cause.
04In flue gas, MgO absorbs SO₂ to form magnesium sulfite and sulfate, and the magnesium can be recovered and returned to the process.
The trade-off you should plan for
MgO is a powder that must be slurried and dosed. Where a ready slurry is easier to handle, Mg(OH)₂ is often the more convenient form of the same chemistry.
Recommended grades
Magnesium Oxide
Light Magnesium Oxide
Calcined at a lower temperature than heavy MgO, leaving a low bulk density and a high specific surface area. Reacts faster and occupies more volume per kilogram — the conventional choice for rubber, and the wrong choice if your process is volume-limited.

Magnesium Oxide ZH-M600
Active Magnesium Oxide ZH-M600
High-activity magnesium oxide with a specific surface area of at least 175 m²/g. A high-functionality fine inorganic material: adsorbs more, cures faster and reinforces more per kilogram than a dense grade.

Common questions
Can I get third-party inspection before shipment?
Yes. Independent inspection before loading is supported on request; you nominate the inspection company and the scope. Every batch is released against its own certificate of analysis in any case, and the tested value — not a range — is reported for every parameter.
Which heavy metals do you report?
Lead, arsenic, cadmium and mercury, tested per batch on food and pharma lots, with the measured value on the COA.
Which certifications do you hold?
We hold ISO 9001 for the design, development, manufacture and sales of magnesium compounds. No certificate number, issuing body or validity date is published until the client supplies them. Other certifications, including REACH registration, food-contact and pharmacopoeia documentation, halal and kosher, are confirmed per destination market before quotation — ask our team for the current document set.
