AⅢ BⅤ型异构化合物热容优化
Correlative Optimization of Heat Capacities of Isostructural Compounds
摘要
Abstract
A semi-empirical approach to the critical analysis of thermodynamic data is proposed and applied in this work.A critical analysis of heat capacities of the sixteen isostructural AⅢBⅤ compounds was then made based on the correlative optimization method.A set of mutually agreed equations C0P =a + b ·10-3 · T-c · 105 · T-2was proposed to describe the heat capacities of these phases.Two continuums of relations C0P (T) vs.logarithm of the sum of atomic numbers of elements A and B were obtained for the AⅢBⅤ phases,of both sphalerite and wurtzite types,in the temperature range from 260 to 1 500 K.Based on the proposed equations,heat capacity values were predicted for the previously unstudied (or poorly studied) phases TlN and AlP within the temperature ranges of 260 ~ 1018 K and 260 ~ 1 500 K,respectively.The proposed correlative method of thermodynamic functions can be applied to other inorganic and organic isostructural compounds,other different groups of isostructural organic and inorganic compounds.关键词
