Caustic Calcined Magnesia (CCM) — MgO 85–95%
Caustic calcined magnesia (CCM) calcined at 700–1000 °C with high chemical activity. MgO grades 85%, 90%, 92%, 94% and 95%; custom mesh from 120 mesh powder to 1–3 mm granules.
Our factory supplies full-series caustic calcined magnesia (CCM), manufactured by calcining natural magnesite ore at 700–1000℃, featuring high chemical activity and stable composition. We provide abundant MgO purity options: 85%, 90%, 92%, 94%, 95% multiple grades to satisfy different industrial standards.
Raw materials go through magnetic separation and impurity removal to cut iron, silicon and foreign contaminants effectively, low impurity content guaranteed. We fully support customized processing: regular sizes include 120mesh, 200mesh, 325mesh fine powder, 0-1mm, 1-3mm granules; all grain sizes can be tailored as clients’ technical requirements.
This multi-spec light burned magnesia is widely used for magnesite building boards, magnesium cement, flue gas desulfurization, wastewater treatment, abrasives, feed additives and refractory raw materials. Stable batch quality, flexible specification adjustment, factory direct supply for global buyers.

Frequently Asked Questions
Which magnesia products do you supply?
Caustic calcined magnesia (CCM, MgO 85–95%), dead burnt magnesia (DBM, MgO 96–99%), electro-fused magnesia (MgO ≥ 98%), high purity magnesia sand, plus magnesium sulphate heptahydrate (99.5%) and monohydrate.
What is the difference between caustic calcined, dead burnt and fused magnesia?
CCM is calcined at 700–1000 °C and is chemically reactive, used for magnesium cement, desulphurisation and feed. DBM is sintered above 1600 °C for high density and is the base for refractory bricks. Fused magnesia is arc-melted above 2800 °C, giving the largest crystals and the best slag resistance.
Can I get custom MgO content and particle size?
Yes. MgO can be tailored across 85%, 90%, 92%, 94%, 95%, 96%, 97%, 98% and 99%, with powders from 120 mesh to granules of 0–1 mm, 1–3 mm, 3–5 mm or larger.
Do you provide third-party test reports?
Yes. We test every batch in-house and can arrange SGS or other third-party inspection on request, at the buyer's cost.
