XRD Chemical is a professional Magnesium Oxide manufacturer and supplier in China, offering high-purity magnesium oxide (MgO) in multiple grades for animal feed, fertilizer, refractory, and industrial applications.
Magnesium oxide is a white, hygroscopic solid with the formula MgO and a molecular weight of 40.30 g/mol. It is produced primarily by calcining magnesium carbonate (magnesite) or magnesium hydroxide at high temperatures. It has an extremely high melting point of approximately 2,800°C and excellent thermal stability, making it a key material for high-temperature applications. Different calcination temperatures produce different grades: light-burned (caustic calcined) magnesia at 700-1,000°C with higher reactivity and surface area, and dead-burned magnesia at 1,500-2,000°C with lower reactivity but higher density for refractory applications.
The primary applications of magnesium oxide span multiple industries. In animal feed, it provides bioavailable magnesium for livestock nutrition. In agriculture, it serves as a magnesium fertilizer to correct soil deficiencies. In the refractory industry, dead-burned magnesia is essential for manufacturing basic refractories used in steel-making furnaces, cement kilns, and glass tanks. Additional applications include flue gas desulfurization, wastewater neutralization, pulp and paper processing, and as a raw material for producing other magnesium compounds such as magnesium chloride and magnesium sulfate.
