Phase diagram of a binary mixture in a closed cavity.
Normally, the phase diagram is reported as a property of the binary mixture. We show that the phase diagram (that is, the zones of thermodynamic stability of the states of the binary mixture) is also affected by the size of the container. We investigate the thermodynamic stability of the binary mixture in a closed cavity, and identify the zone in parameters where the binary mixture is heterogen...
متن کاملPhase Diagram of the TbBr3-KBr Binary System
The phase equilibrium of the TbBr3-KBr has been established by Differential Scanning Calorimetry. This system has the three compounds K3TbBr6, K2TbBr5, and KTb2Br7 and two eutectics located at (xTb = 0.163 (885 K) and (xTb = 0.433 (697 K). K3TbBr6 undergoes a solid-solid phase transition at 691 K and melts congruently at 983 K with the corresponding enthalpies 8.0 and 48.0 kJ mol−1. K2TbBr5 mel...
متن کاملPhase diagram of highly asymmetric binary hard-sphere mixtures.
We study the phase behavior and structure of highly asymmetric binary hard-sphere mixtures. By first integrating out the degrees of freedom of the small spheres in the partition function we derive a formal expression for the effective Hamiltonian of the large spheres. Then using an explicit pairwise (depletion) potential approximation to this effective Hamiltonian in computer simulations, we de...
متن کاملBiMn Binary Phase Diagram in High Magnetic Fields
To examine magnetic field effects on the BiMn equilibrium phase, a high-magnetic fields differential thermal analysis (HF-DTA) was performed for fields up to 18T and temperatures ranging from 300 to 753K. For zero field, the peritectic temperatures Tp1 (BiMn1.08 + Bi-rich liquid1⁄4 BiMn) and Tp2 (¡Mn + Bi-rich liquid1⁄4 BiMn1.08), and the eutectic temperature TE (the Bi-rich liquid 1⁄4 Bi soli...
متن کاملPhase diagram of a binary symmetric hard-core Yukawa mixture.
We assess the accuracy of the self-consistent Ornstein-Zernike approximation for a binary symmetric hard-core Yukawa mixture by comparison with Monte Carlo simulations of the phase diagrams obtained for different choices of the ratio alpha of the unlike-to-like interactions. In particular, from the results obtained at alpha=0.75 we find evidence for a critical endpoint in contrast to recent stu...
