Overview
Dolomite is the only common mineral that delivers both CaO and MgO in a single feedstock, which is why glassmakers specify it rather than blending limestone with magnesia. In coatings and plastics it acts as a bright, hard functional filler; in construction and environmental applications it is used for mortar, concrete and flue gas desulphurisation. Our dolomite standard TDHX-Dolomite-2025-08 specifies CaO 27–35%, MgO 22–30%, SiO₂ ≤8%, Fe₂O₃ ≤0.5% and whiteness 80–95%, across 200 to 2000 mesh.

What are the CaO and MgO contents of your dolomite powder?
Our dolomite standard TDHX-Dolomite-2025-08 specifies CaO 27–35%, MgO 22–30%, SiO₂ ≤8%, Fe₂O₃ ≤0.5% and whiteness 80–95. Individual grades sit inside that window; the TDS is available for download on this page. Tell us your target chemistry and we will confirm which grade matches.
Which industries use dolomite powder?
Glass and ceramics (CaO–MgO source), coatings and plastics (functional filler), construction (mortar and concrete), and environmental protection (flue gas desulphurisation).
Why is dolomite powder used in glass melting?
Dolomite supplies both CaO and MgO in one raw material, which lowers the melting temperature, aids refining, and improves the thermal and chemical durability of the finished glass.
Can dolomite powder be customised for my process?
Yes — mesh size from 200 to 2000 mesh, whiteness 80–95, and CaO/MgO ratios can all be adjusted. Free samples are available for bench testing.
