    Sulfide and sulfate solid solubility in . - SpringerLink

    In the present work the solid solubilities of CaS and CaSQ, in burnt lime were investigated by equilibrating lime with CO-CO2-SO2 mixtures at temperatures from 950 to 1300°C. Also, the equilibrium constants for the formation of CaS and CaSO4 were determined. At high oxy-gen activities, corresponding to a CO2/CO ratio >100 in the gas, the sulfur dissolves in lime primarily as sulfate ions.

    Dolomite is sometimes used both in the raw and calcined form as refractory material for hearth maintenance and for banking door in open hearth furnaces. For most refractory uses, it is desirable to subject the dolomite to a heat treatment at a high temperature of the order of 1700ºC, to shrink the material thoroughly and render it less reactive.

    Magnesium (Mg) is a silvery white metal that is similar in appearance to aluminum but weighs one-third less. With a density of only 1.738 grams per cubic centimetre, it is the lightest structural metal known. It has a hexagonal close-packed (hcp) crystalline structure, so that, like most metals of this structure, it lacks ductility when worked at lower temperatures.
