Title: Diffuse Phase Transition In Non-Stoichiometric LiRbSO4 Crystals
Author: Al Houty, L [لطيفة ابراهبم الحوطي]
Abstract: The influence of changing the ratio of ^504 on the structure transition of (Rb,Lii_,)2S04, LRS crystals, where x ranged from 0.1 to 0.7, was studied by thermal analysis techniques in the temperature range 300 - 600 K. Multiple peaks in the DTA traces were observed for crystals having x = 0.1 and x = 0.2. The values of Gp decreased while that of T, increased with increasing Rb+ content. The excess of the specific heat for LRS crystals showed a broadening in the temperature dependence especially for samples enriched with Rb"*". These results could be considered on the development of the ordering of SO., and LiO, and in their arrangementتم دراسة تأثير تغير نسبة كبريتات الليثوم على التحول البللوري لبللورات .
