Phase equilibria from molecular simulation
Phase equilibria are at the heart of many properties of substances, such as their solubility, manufacturability, and stability. They are of significant industrial and commercial interest, perhaps most importantly to the pharmaceutical industry where drug stability and solubility are two of the …

Phase equilibria in iron phosphate system
… to synthesize iron phosphate compounds, study phase equilibria in the iron phosphate system, focusing on the glass forming area, and investigate glass formability and properties based on the liquidus regions. Twelve iron phosphate compounds were successfully prepared and studied in terms of …

Calculation of chemical and phase equilibria
The computation of chemical and phase equilibria is an essential aspect of chemical engineering design and development. Important applications range from flash calculations to distillation and pyrometallurgy. Despite the firm theoretical foundations on which the theory of chemical equilibrium is …

Phase equilibria studies and beneficiation of titaniferous slags
… attributed to the presence of chemically inert phases, like the spinel solid solution [Mg(Al,Ti,V)2O4] that cannot be handled by the available titania slag upgrading technologies. The understanding of phase relations in titaniferous slags is thus important in order to be able to implement a …

Phase Equilibria in Systems Containing Hydrocarbon, Water and Methanol
… because of near wellbore condensate buildup. The phase behavior of systems containing hydrocarbon, water and methanol was reviewed based on past experimental work. The main objective of this report is to review experimental phase behavior data available for hydrocarbon, water and methanol …

Phase equilibria in the LiF-AlF₃Na₃AlF₆ system
The phase equilibria relationships in the Na₃AlF₆-AlF₃-LiF ternary system have been investigated using a combination of quenching, optical microscopy, DTA, and x-ray powder diffraction techniques. The compatibility relations at 500°C, the binary system Na₃AlF₆-Li₃AlF₆, and the ternary liquidus …

Phase equilibria in the system Na₃AlF₆-Al₂0₃- NaCaAlF₆
The NaCaAlF₆-Al₂O₃ and Na₃AlF₆-Al₂O₃-NaCaAlF₆ phase diagrams were determined using DTA, x-ray diffraction, quench analysis, and optical microscopy. The NaCaAlF₆-Al₂O₃ system was a simple eutectic system with the eutectic located below 0.5 weight percent NaCaAlF₆. The ternary system was a eutectic …

Phase equilibria and volumetric properties for the system NaCl-CaCl₂-H₂O
Low temperature phase relations in the ice-stable field of the system NaCl-CaCl₂-H₂O were determined under 1 atm. total pressure along the NaCl-H₂O and CaCl₂-H₂O binaries and along five pseudobinaries with constant NaCl/(NaCl+CaCl₂) weight ratios. The results are in excellent agreement with …

Phase equilibria and thermodynamic studies in the system Ca0-Fe0-Fe₂0₃₋Si0₂
"A study of phase relations and thermodynamic properties of phases in the system CaO-FeO-Fe₂O₃-SiO₂ was conducted at 1450°C and 1550°C. The region of stability of the different phases was determined by microscopic examination of the specimens. The thermodynamic properties of liquid were determined …
