The low-temperature (T<120 degrees C) H (sub 2) O-RbCl phase diagram comparison with other water-alkali chloride systems
Index Terms/Descriptors
Abstract
The eutectic T in the H (sub 2) O-RbCl system was determined from synthetic fluid inclusions, using a 39.99 + or - 0.01 wt.% RbCl solution. By isolating the last solid (RbCl) and freezing the remaining liquid, the T at which the liquid begins to melt was accurately measured (-16.4 + or - 0.1 degrees C) during subsequent heating measurements. The ice-melting and salt-melting curves were fitted using a constrained least-squares procedure and the eutectic composition was calculated (39.55 + or - 0.01 wt.% RbCl). The phase diagram is similar to those of H (sub 2) O-KCl and H (sub 2) O-CsCl systems, but differs from those including the smallest alkali ions (LiCl and NaCl) which are complicated by the occurrence of hydrates.
