The phase diagram for Fe2O3 - Fe3O4 - CsFeO2 system has been constructed to investigate the chemical composition and to obtain the data on the mutual transitions. The diagram using allows to calculate quickly the phase and chemical composition of the compounds constituting the catalytically ...
攀钢钒渣主要包括V2O3、FeO、Fe2O3、SiO2、CaO、MnO、TiO2等[27-29]组元,考虑到实际钒渣组元中FeO和SiO2的含量较大,V2O3是钒在渣中存在的主体价态形式[19,30,31],而且FeO和V2O3形成钒铁尖晶石有利于钒更多的进入钒渣中,所以钒氧化物炉渣的一个基本相图是FeO-SiO2-V2O3三元系。迄今为止,只有FeO-SiO2二元系...
③1350℃时FeO-SiO2-V2O3(MnO, TiO2=10%)渣系的主要物相是尖晶石相(FexV3-xO4(MnV2O4) Fe2+yTi1-yO4, 1≤x≤2, 0≤y≤1)和橄榄石相(Fe2SiO4)。灰白色物相为尖晶石相,黑灰色物相为硅酸盐相,尖晶石相以粒状为主。V聚集在尖晶石相中,Si聚集在硅酸盐相中,而Fe、Mn、 Ti和O存在于两种相中。
Phase diagram measurements are used to derive the thermodynamic properties, and vice versa. The optimizations of the subsystems, i.e. FeO–Fe2O3 [16], CaO–SiO2 [15], CaO–FeO–Fe2O3 [17] and FeO–Fe2O3–SiO2 [18], have been reported previously....
A part of the phase diagram of the system PbO-B 2O 3-Fe 2O 3-Y 2O 3 has been investigated. The system has been treated as the "ternary" system S-Fe 2O 3-Y ... HD Jonker - 《Journal of Crystal Growth》 被引量: 53发表: 1975年 Phase-equilibrium data and liquidus for the sy...
The direct evidence that no Fe2O3 nanoparticles could be observed by a large area scan excludes the origin of any magnetism from a second phase. Furthermore, our high resolution STEM-EDX mapping results showed no localized distribution of Fe atoms in a specific layer between the two Bi2O2 ...
A Study of Liquidus Temperature of the Iron Oxide Rich Corner of the FeO–Fe2O3–SiO2–TiO2 System at Different Oxygen Pressures Liquidus temperatures in the system FeO–Fe2O3–SiO2–TiO2 at five oxygen pressures in the range 2 × 10−2 to 10−6 atmospheres have been measured for......
