Looking for high-performance magnesium oxide (MgO) for your food, pharma, or industrial applications? Understanding the difference between brine-based and calcined magnesite MgO is essential to making the right choice.
At Shandong Runfu Ca Mg Chemical Technology Co., Ltd., we are a leading manufacturer of synthetic (brine-based) magnesium and calcium salt products, with customizable solutions and global export services.

Brine-based MgO is produced from natural brine or seawater, using chemical precipitation and low-temperature calcination. This method delivers:
Ultra-high purity (>99%)
Low impurity content
Customizable particle size and surface area
Superior solubility and reactivity
Ideal for:
Food additives
Pharmaceuticals (antacids, supplements)
Cosmetics
Environmental protection
Ceramics
Electronic materials
This MgO is made by mining natural magnesite (MgCO3) and calcining it at high temperatures (~1500°C). It is generally:
Lower in purity
Less reactive
Richer in iron, calcium, and silicon impurities
Common uses:
Metallurgy
Refractory bricks
Agriculture and fertilizer industries
Synthetic MgO from brine can reach 99.5%+ purity, essential for sensitive applications.
Adjust particle size, shape, and moisture content based on your needs.
Meets strict international standards like USP, FCC, food grade, and pharma grade.
Low-temperature calcination ensures lower emissions.
Over 10 years of experience in brine-based magnesium salt production
Fully customizable products: mesh size, granule shape, purity, packaging
Professional certifications: ISO, Halal, Kosher, REACH, SGS
Global shipping & MOQ as low as 1 ton
