Sintered magnesium oxide, also known as dead burned magnesite, is the result of the sintering process of raw magnesite (magnesium carbonate) at 1800°C.

Our sintered magnesium oxide product line is commercially known as DBM M and DBM P, which are produced from the single-burning process in vertical kilns, reaching up to 94% MgO content, resulting in products with a density of 2.95g / cm³ and 3.05g / cm³, of greater chemical stability, resistant to corrosion and high refractory properties.


The DBM M and DBM P have an excellent mechanical and chemical resistance, in addition to a great granulometric diversity.
