Coated magnesium granule is used as desulfurizer and deoxidizing agent in superior steel-making with low sulfur.
Its duration of fire resistance is more than 15 seconds in molten iron at 1000-1300℃ and it can remove the sulfur to less than 0.001%.
It is used in producing ductile iron; in petroleum extraction industry, it can retore and accelerate the pressure for drilling and the speed of drilling footage.
In chemical and military industry, it is used as dehydrating agent and combustion adjuvant, and also it is a good metallurgy material of magnesium alloy powder.
