Questions regarding magnesium-based desulfurization and light magnesium oxide
Thread Content
I would like to ask the experts: for magnesium-based desulfurization, is it better to use magnesium oxide with a purity of 85 or 80? I consulted a manufacturer of magnesium oxide, and they said that the 80-grade variety has better activity than the 85-grade one; this seems unlikely. Could anyone recommend some manufacturers that specialize in producing magnesium oxide?
It is necessary to test the activity of the magnesium oxide you have purchased. Magnesium oxide from different manufacturers varies, even when it has the same composition, depending on the calcination process used. The magnesium oxide produced by our company is primarily intended for the desulfurization industry and features high activity.
I think 85-grade powder has a higher purity than 80-grade powder, with fewer impurities from post-treatment; it should have no direct impact on activity
80 generally refers to lightly calcined magnesium oxide, which has high activity. 85 generally refers to dead-burned magnesium oxide, with low activity. The magnesium sulfate industry generally chooses grades below 80
