Heavy Magnesium Oxide

Our high-density Heavy Magnesium Oxide offers superior powder flow and low dust levels. It packs tightly and evenly, preventing equipment clogging and ensuring precise dosage during tableting, ceramic press molding, and electrical insulation manufacturing.

Caustic Calcined Magnesia (CCM)

We supply Caustic Calcined Magnesia for large-volume industrial applications. It offers controlled reactivity for safe, cost-effective pH neutralization, heavy metal precipitation, and soil remediation without causing dangerous temperature or pH spikes.

Feed Grade Magnesium Oxide

We rigorously test our feed and agricultural Magnesium Oxide to ensure full compliance with heavy metal safety standards (Pb and As). Its high bio-availability prevents hypomagnesemia (grass tetany) in cattle and provides essential magnesium for high-yield crop fertilizers.

Magnesium Oxide Field Performance & Key Applications

We supply high-reactivity Magnesium Oxide tailored to demanding global production environments. Here is how our material delivers reliable performance across core industrial sectors:
