High Purity Magnesium Oxide — Manufacturer & Supplier | Magnesium Home

High purity magnesium oxide (≥99.5–99.9% MgO) is produced from high-quality brine and ore through a controlled carbonization–calcination process. With extremely low chloride, sulfate and heavy-metal impurities, it is the material of choice for electronic ceramics, optical glass, catalyst supports and advanced pharmaceutical intermediates.
