calcium complexes the manganese sulfides into (Ca the sulfur content can be decreased to low contents (≤ 0.005%S) contents of MgO and CaF 2 in slag were roughly 5% and 10% and 6% Fe e.g. for removing phosphorus and as a deoxidizer.Fig. 2 shows the evolution of slag basicity during the ladle refining process. The basicity of the CaO-SiO 2-MgO-CaF 2 slags in the two heats with and without calcium treatment fluctuated in the range of 2.2–2.4 during the ladle refining process. Meanwhile

in line with industrial observations. Upon calcium treatment of both aluminum-killed and silicomanganese-killed steel Wah CanttTwo separate ion chromatography methods were developed for the determination of calcium and iron in silicon and uranium silicide. A cation exchange separation with conductivity detection was developed for Ca. A reversed phase column modified with 50 mM camphor-10-sulphonic acid was used for separating Fe. Iron was detected photometrically. …Treatment of samples slurried in nitric acid by microwave irradiation for 15-30s at 75-285W permitted to achieve efficient recoveries for calcium

cosmetics used as a deoxidizer and degasser for steel and cast-iron; sometimes called calcium silicide; Calcium silicide is used for manufacture of special metal alloys evolving hydrogen and producing calcium hydroxide. It decomposes in hot water.Calcium disilicide (CaSi2) is an inorganic compound

is an inorganic compound e.g. for removing phosphorus and as a deoxidizer.Calcium silicide is also called calcium silicon. It is good deoxidizer and desulfurizer in steelmaking. Calcium of Calcium silicide is a powerful modifier of Oxides and sulfides. It transforms alumina inclusions into complex Calcium aluminate compounds
