A2 A phase diagram is a graph of the physical states of a substance under different conditions of temperature and pressure. A phase change occurs when we cross the lines on the phase diagram.The triple point is the point on the phase diagram at which all three distinct phases of matter(sol...
Its general definition refers to the equilibrium state and stability limits of particular phases, which set the stage for its terms of use. In the literature, however, a phase diagram often appears as an umbrella category for any pressure鈥搕emperature chart that presents not only equilibrium ...
Supercritical fluid, they were, it’s on the board, we can’t understand the process of extracting the caffeine from the coffee if we don’t get this concept down pat.In order to do that, let’s take a look at the phase diagram. This should be a review.So, the phase diagram, it...
Phase equilibria in the Ce2O3-K2O-P2O5 system Ce2O3-K2O-P2O5ternary system has been investigated by thermoanalytical methods (DTA, DSC), powder X-ray diffraction, XPS and IR spectroscopy. The existence... I Szczygieł,A Matraszek,T Znamierowska - 《Journal of Thermal Analysis & Calorim...
We investigate the properties of the zero-field O(n) model on the honeycomb lattice outside the range of presently available exact solutions. To this purpose, we make use of finite-size scaling and transfer-matrix techniques. Our results confirm the expected phase diagram of the O(n) model ...

The paper reviews the controversy on the shape of the fcc-based phase diagram near the triple point among the disordered (A1), Ll_2 and Ll_0 phases. The discrepancy was originally between the cluster variation method (CVM) results and Monte Carlo (MC) simulation results, but the controversy...
We arrive at a phase diagram which shows a ferromagnetic ground state for 0.1<=x<=0.15 followed by a canted antiferromagnetic phase at higher temperatures, not in agreement with present canonical conjectures. The phase diagram indicates the importance of structural aspects and superexchange ...
