A generalized thermodynamic expression of the liquid Al–Ga–P–As alloys is used in conjunction with the solid solution model in determining the solid–liquid equilibria at 1173 K and 1273 K. The liquid solution model contains thirtyseven parameters. Twentyfour of them pertain to those of the six constituent binaries, twelve refer to the specific ternary interactions. Additionally the liquid solut...

The solid–liquid phase diagrams of two binary mixtures of saturated fatty acids, formed by caprylic acid (C8:0) + myristic acid (C14:0) and lauric acid (C12:0) + myristic acid (C14:0), were measured using high pressure microscopy in the range of 0.1–90 MPa. It is shown that unlike for other long chain alkyl compounds such as alkanes the phase diagrams are only slightly affected by the pressure,...

The objective of the present work is to investigate full phase diagram a binary system composed carbon dioxide and heavy paraffin. An alkane with an odd number was chosen since mixtures paraffins crystallize in orthorhombic structure like pure do. normal-heptadecane taken into consideration for this study as it has melting temperature close ambient condition (295 K). consists measuring both flu...

Isoplethic thermal analysis was used to determine the solid-liquid-liquid equilibria in the ternary system water-sodium sulfatepiperidine. The changes in state observed on the thermogram recorded during the displacement in a quasi-binary section permit the identification of the different phases and the delimitation of the corresponding equilibrium domains. Two isotherms were established at 25°C...

A Monte Carlo simulation study is made of the phase diagram of the restricted primitive model and of the solid± liquid and solid± solid phase coexistence curves in particular. At low temperatures, there is liquid± bcc coexistence and with increasing density there is bcc± fcc coexistence. These coexistence curves end in a triple point (liquid± bcc ± fcc) above which only liquid± fcc coexistence ...
