Abstract
Section titled “Abstract”The pressure-volume-temperature equations of state have been constructed by combining experimental data and semiempirical estimations for a number of compounds recently synthesized under extreme pressure-temperature conditions. The solids with various bonding types were considered: covalent hard and superhard boron-rich and diamond-like compounds (e.g. B6O, B13N2, BP, c-BC5, and nano-cBN), ionic semiconductors (e.g. Mg2C and Mg2C3), as well as intercalation compounds (e.g. clathrates Na4Si24 and Na24+xSi136), and simple substances (e.g. boron allotropes γ-B28 and t’-B52, and open-framework silicon allotrope o-Si24 with quasi-direct bandgap). We also showed how the reliable p-V-T equations of state may be constructed using different types of data available.
