摘要
在-190 ~ 120℃范围内,研究了单斜斜Rb 1- x Cs x d2po4体系晶体的介电、热释电和热性能。在整个x范围内建立了系统的相图。x =0的晶体有三个相,按温度递减的顺序分别为I、II、III。当x从0开始增大时,在III相和II相之间出现铁电相IV,相TV的温度范围扩大。III-IV和IV-I的过渡熵明显小于III-II、i - i和IV-II的过渡熵。
Dielectric Studies of Monoclinic Rb 1− x Cs x D 2 PO 4 on the Phase Transitions
Dielectric, pyroelectric and thermal properties of the crystals of monoclinic Rb 1- x Cs x D 2 PO 4 system were studied from -190°C to 120°C. The phase diagram of the system was established in the whole range of x . The crystal of x =0 has three phases denoted as I, II and III in order of the descending temperature. As x increases from zero, a ferroelectric IV phase appears between the phases III and II, and the temperature range of the phase TV spreads. The III–IV and IV–I transition entropies are distinctly small in comparison with those for the III–II, II–I and IV–II transitions.
