- Аннотация: Our previous review articles [1] evidenced the relation of thermodynamic data with the Periodic Law. A strict relationship could be established between the enthalpy of formation, melting point and the components atomic numbers in the semiconductor A<sup>III</sup>B<sup>V</sup> phases, with diamond-like structures of sphalerite and wurtzite types. The proposed model was used to critically assess the thermodynamic properties of isostructural compounds. The relationship between the reduced enthalpy, standard entropy, reduced Gibbs energy and the sum of the atomic numbers (Zi = ZA + ZB) has been used to critically assess the thermodynamic properties of AIIIBV phases. For the AIIIBV phases in the solid-state, the Similarity method was applied to critically analyze heat capacities. For these AIIIBV phases (sphalerite and wurtzite types), heat capacities relationship with the logarithm of elements atomic numbers was used to estimate the continuum above 298 K [2]. The Similarity Method was also used for the specific heat critical analysis for the fourth group (C, Si, Ge, Sn), AIIIBV and AIIBVI isostructural phases in the solid-state. The dependence of the heat capacities from 0 to 1500 K follows certain regularity. Phases with the same element atomic numbers (Z) sum, such as BN (hex) Z=12 and glassy pure carbon Z=6; BP and AlN (Z=20); AlP (Z=28) and pure Si (Z=14); BAs and GaN (Z=38); AlAs and ZnS (Z=46); AlSb, GaAs, InP (Z=64) and pure Ge (Z=32); GaSb, InAs, and CdSe (Z=82); InSb, CdTe (Z=100) and pure grey Sn (Z=50); have the same heat capacity experimental values in the solid-state within the experimental uncertainty [3]. This rule can be applied to different isostructural compounds. References: 1. V.P. Vassiliev, B. Legendre, V.P. Zlomanov.
