Magnesium oxide (MgO) is an active mineral compound obtained by roasting natural raw materials. The product is distinguished by its high magnesium oxide content (min. 73%) and the presence of additional minerals such as CaO, SiO₂ and Fe₂O₃. It comes in the form of light brown granules with a grain size of 0.0–0.5 mm.
Thanks to its chemical properties, it is widely used in agriculture and industry. In agriculture, it improves soil quality and is a source of easily absorbable magnesium, while in the chemical industry it serves as a versatile technological raw material.
