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. Sulfur Cycle- Definition, Steps, Examples, Significance, Human Impacts The sulfur cycle is a biogeochemical cycle consisting of various processes that together enable the movement of sulfur through reservoirs. The SO2 present in the atmosphere reaches the biosphere as the gas dissolves in the rainwater to form weak droplets of sulfuric acid. (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...
