Dead Burned Magnesite
Dead Burned Magnesite is selected from natural magnesite, it is produced by mine-selecting, purifying, calcining in shaft kiln. It is an ideal material for unshaped refractory material, the final products are used in open hearth furnace, electric furnace bottom and furnace’s lining tamping. Magnesium is a chemical element with the symbol Mg and atomic number 12. Its common oxidation number is +2. It is an alkaline earth metal and the eighth most abundant element in the Earth’s crust and ninth in the known universe as a whole. Magnesium is the fourth most common element in the Earth as a whole (behind iron, oxygen and silicon), making up 13% of the planet’s mass and a large fraction of the planet’s mantle. The relative abundance of magnesium is related to the fact that it easily builds up in supernova stars from a sequential addition of three helium nucleic to carbon (which in turn is made from three helium nuclei). Due to magnesium ion’s high solubility in water , it is the third most abundant element dissolved in seawater.
