(PDF) The liquid-liquid phase diagram of sulfur+biphenyl We have studied the liquid-liquid phase diagram of sulfur+biphenyl. sulfur+biphenyl is described well with β=0.25, the value appropriate for a nonsymmetrical tricritical point. The polymer‐poor branch could not be described by any of the values of β thought to be possible (i.e., 0.25, 0.325, 0.50, 0.67, or... Диаграмма состояния системы Cr-S The solid-state phase relations above ~700 C are based mainly on the detailed sulfur pressure measurements of [77Rau]; those below ~700 C are based primarily on the X-ray studies of S at ~1300 C. Based on the stability diagram, a peritectoid decomposition of Cr3S4 at 1152 C is suggested.

How would you explain the phase diagram of sulphur? | Socratic The phase diagram of sulfur is The diagram is complicated by the fact that sulfur can exist in two crystalline forms: rhombic and monoclinic. A phase diagram is a chart that shows the conditions of pressure and temperature at which distinct phases occur and coexist at equilibrium.
