Kambara Reactor (KR) desulfurization slag used as slag-making material for converter smelting can promote early melting in the initial stage and improve efficiency of dephosphorization. However, its direct utilization a slagging increase sulfur content molten steel since KR contains 1~2.5% sulfur. Therefore, this research focuses on effect basicity precipitation behavior occurrence state order ...

The concept of optical basicities initially developed by Duffy for solid oxides was successfully transferred to low melting salts such as ionic liquids (ILs). Several ionic liquids (ILs) were doped with Mn(NTf(2))(2) (NTf(2) = bis(trifluoromethanesulfonyl)imide) as a probe to investigate the IL anion basicity by means of UV-Vis spectroscopy. The (6)A(1)-->(4)A, (4)E(G) transition band of Mn(2+)...

The phosphorus partition between the unkilled liquid crude steel and high basicity (CaO/SiO2 = 4.2), basic oxygen furnace (BOF) slags with varying compositions of Al2O3, TiO2, MnO is studied at temperatures 1600 1650 °C. tests are conducted in both “slag-to-metal” “metal-to-slag” directions for durations 30 60 min. measured results compared values reported literature found to be good agreement ...

double system of exponents with complex-valued coefficients is considered. under some conditions on the coefficients, we prove that if this system forms a basis for the morrey-lebesgue type space on $left[-pi , pi right]$, then it is isomorphic to the classical system of exponents in this space.

The influence of the Lewis basicity of alkali polysulfide fluxes (A(2)S(x)) (A = alkali) as a function of x on the respective reactivities of Pb and Sn with Ge was studied and found to be strong. Cs(4)Pb(4)Ge(5)S(16), K(2)PbGe(2)S(6), and K(4)Sn(3)Ge(3)S(14) could be prepared only under low basicity with S/A(2)S ratios of > or =11. These compounds display complex frameworks and are semiconducto...

Kinetics of reversible oxygenation and carbon monoxide complex formation of the simple heme compounds pyrroheme-N-[3-(1-imidazolyl)propyl]amide and pyrroheme-3-(3-pyridyl)propyl ester have been measured in different solvent environments. The oxygen on and off rates and equilibria of these compounds can be made to closely match those of myoglobin, of hemoglobin alpha chains, or of the various st...

The gas phase basicity of the title compound has been determined to be greater than that of putrescine, making it the most basic primary diamine measured to date.

In order to clarify the mechanism for increase in oxygen content during electroslag remelting, this paper analyzes detail effect of slag components on gas and number, size composition inclusions ingots. The results show that, when CaF2-MgF2-CaO-MgO-SiO2 system is used ingots decreases clearly with basicity. When basicity 14~3.3, only 9~11 ppm. drops 2.3, increases 20 high also leads a decrease ...
