J. Cent. South Univ. (2016) 23: 1332-1338 DOI: 10.1007/s11771-016-3184-z Plotting and application of predominance area diagram of Me-S-O system based on topological rules XIE Fu-chun(谢富春)1, 2, YIN...: The mathematical topological rule was applied to plot the predominance area diagram. Based on the analysis of the mutually conjugated, only two diagrams were the best topological embryonic graphs to build......

concentration on the zinc solubility, which can provide thermodynamic references for the zinc hydrometallurgy. Key words: thermodynamics; predominance diagram; zinc hydrometallurgy; ammonia leaching 1... to get a series of closed areas in -lg[NH3]T-pH plane. Thus the predominance diagram can be constructed as a function of [NH3]T versus pH. Smaller step of [NH3]T, [Zn(II)]T and pH will produce more......

of Architecture and Technology, Xi’an 710055, China) Abstract: Using TiO2, B2O3 and C as raw material, TiB2 powder was synthesized by carbothermal reduction. The predominance area phase diagram (PAPD) of Ti-C-O system and B-C-O system were plotted by thermodynamic analysis. In addition, the superposition of predominance area phase diagram of TiO2-B2O3-C system was achieved. The reaction mechanism......

Trans. Nonferrous Met. Soc. China 25(2015) 960-965 Plotting and application of predominance area diagram of In-S-O system based on topological rules Fu-chun XIE1,2, Zhou-lan YIN1, Jun TAN1, Chang... was proposed to plot the predominance area diagram. Based on the phase rules, the components of In-S-O system were analyzed and the coexisting points of three condensed phases were determined. Combined......
of predominance area diagram of Pb-S-O system based on topological rulesYAO Teng-meng1, TAN Jun1, LIU Chang-qing1, LI Jie1, CHEN Qi-yuan1, WANG Hui2, LIAO Zhou2, ZHANG Ping-ming1(1. Key Laboratory.... The results show that the β plane- topological diagram is in accordance with the predominance area diagram of Pb-S-O system calculated by traditional methods, indicating that this method is feasible to plot......
phases in kiln slag iron concentrate are Fe, FeO, FeS, Fe2O3, Fe3O4 and FeSiO3. The φ-pH predominance diagram of Fe-Cl--H2O system, as well as the lg c -pH diagrams of FeS, FeO, FeSiO3-H2O system and FeS... slag iron concentrate; leaching; thermodynamic analysis; φ-pH predominance diagram; lg c-pH diagram 我国2011年金属锌产量达446万t,其中约85%采用湿法生产.湿法炼锌有常规浸出,高温高酸浸出,常压及高压氧浸[1]等多种工艺,在我国均得到应用,其中常规浸出工艺产量约占我国湿法炼锌总产量的50......
, the predominance area diagram of the Mn-S-O system at different temperatures was constructed based on the thermodynamic data obtained from the literatures. It is seen from this figure that flue-gas... the possibility of desulfurization by selective sulfation without ferric sulfate forming. A multi-stage desulfurization system has been discussed briefly. Key words: predominance area diagram; desulfurization......
