Calcined Magnesite (MgCO₃)

Calcined Magnesite (MgCO₃) is a highly reactive form of magnesium oxide (MgO) produced by calcining (burning) magnesite at a uniform temperature, yielding a high-quality, consistent, finely sized, synthetic magnesium oxide designed specifically for chemical processes requiring a rapid reaction rate and high-purity.

MgO content min 90-96%
Typical Applications

Calcined magnesite has applications in wastewater neutralization, metal precipitation, silica removal, magnesium salt production, acid gas scrubbing, fertilizer production, FCC additive catalyst production, oil drilling fluids, and production of motor oil additives.
