Calcined Magnesite

Calcined Magnesite, also known as burnt magnesite or magnesium oxide, is produced by heating naturally occurring magnesite rock. This process removes carbon dioxide from the magnesium carbonate, leaving pure magnesium oxide (MgO). This product is versatile due to its high heat resistance and chemical stability.
