Products Refractory Industry Caustic Calcined Magnesia

Product Information - Caustic Calcined Magnesia


When naturally occurring magnesium carbonate (magnesite) is fired at around 800-1,500°C it becomes what is known as "caustic calcined magnesia".
The resulting magnesium oxide grains have the outer form of the magnesium carbonate and depending on the firing temperature are porous and more or less reactive due to their large inner surface area.
Grades: Our supply range includes caustic magnesia of various grades and origins for practically all industrial applications. The current focus is on natural magnesium oxide from China and others.


Besides the below mentioned industries caustic calcined magnesia is also used for construction of industrial floors (sorelcement), as magnesium carrier in fertilizers, in production of paper and pulp , in hydrometallurgy, as catalyser, in wastewater treatment, as fuel additive, in cosmetics, sugar refining and polymer additives.
