Magnesium oxide as raw material of magnesium compounds

/

The production of high-purity magnesium containing derivatives requires the reaction of high-quality magnesium oxide (or hydroxide or carbonate) with various other chemical reactants. The oxides have extremely low impurity content, and these elements should usually be excluded from the final product, such as lead, heavy metals and calcium. The reactivity level of magnesium oxide is determined by the properties of magnesium derivatives and their manufacturing methods. Low reactivity grades (designated as SIG, KP, kpll) are characterized by low surface area (about 5 – 20 m2 / g) and activity grades (designated as ra40, ra110, ra150) are characterized by high surface area values (about 50, 120, and 170 m2 / g) and fine particles.
