Magnesium oxide

Magnesium oxide (MgO)—synthetically produced from dolime and magnesium chloride—is Nedmag’s main product. Our magnesium oxide is sold as caustic powder (CCM) in small portions. However, most of our magnesium oxide is processed into Dead Burned Magnesia (DBM), also called sintered magnesia.


"High quality DBM with unrivalled consistency and purity."

Nedmag99 is exempted from registration and evaluation in accordance with Annex V of REACH (naturally occurring minerals that have not been chemically modified. Our products do not classify as "a substance of very high concern."
