Ilmenite is a vital raw material for the production of metal titanium and titanium-containing materials. In this paper, microstructure chemical transformation natural ilmenite in air atmosphere were investigated by analysis XRF, X-ray diffractometer, SEM-EDS. Results showed that untreated had three layers after oxidation at 800 °C 60 min, which Fe2O3, TiO2 inside mixture layer Fe2O3 turn. Subse...

Models of chemical reaction systems can be quite complex as they typically include information regarding the reactions, the inlet and outlet flows, the transfer of species between phases and the transfer of heat. This paper builds on the concept of reaction variants/invariants and proposes a linear transformation that allows viewing a complex nonlinear chemical reaction system via decoupled dyn...

Composition dependence of Young’s modulus in Ti-V and Ti-Nb binary alloys and Sn-added ternary alloys quenched from phase region was investigated at room temperature in relation to the stability of phase. A minimum of Young’s modulus in the binary alloys appears at such a composition that athermal ! phase transformation is almost completely suppressed. Formation of isothermal ! phase by aging a...

Phase behavior of distearoylphosphatidylethanolamine dispersed in excess glycerol has been examined by differential scanning calorimetry. Transformation from lamellar-gel to lamellar crystalline phase was found to take place at temperatures near 74.9 degrees C upon cooling and near 76.3 degrees C during heating scans. The transition can also be observed under isothermal conditions at temperatur...

In this paper, a simple transformation of coordinates is proposed that facilitates the efficient simulation of the non-isothermal lithium-ion pseudo 2-D battery model. The transformed model is then conveniently discretized using orthogonal collocation with the collocation points in the spatial direction. The resulting system of differential algebraic equations (DAEs) is solved using efficient a...
