The isothermal bulk modulus, K T and its pressure derivative, K ′ T , for TlCl and TlBr have been determined up to 6 GPa with energy dispersive X-ray diffraction using synchrotron radiation. Room temperature K 0 T , K ′ 0 T values for TlCl and TlBr are 16.3 GPa, 7.8 and 16.2 ...
The pressure-volume relation and the compression effect on the bulk modulus of tetrahedral compounds such as GaP, InP, ZnS, ZnSe, ZnTe and CdTe are investigated from the electronic theory of solids by using our recently presented binding force, which includes mainly covalent interactions in the ps...

The extrapolated bulk modulus of the high-pressure phase III was determined to be K 0 = 7.1 (8) GPa. The crystal structures in phase III are refined against X-ray powder data measured at several pressures between 0.49 and 4.8 GPa, and the molecules are found to be fully ordered. This ...
The bulk modulus KT can be related to structural parameters and to the sum of the squares of the vibrational frequencies. ∑vi2, for N-atom crystals of cubic symmetry or for any symmetry that contains only one nearest-neighbor distance. Required assumptions are the existence of (1) electrostat...

(Fe0.5Ni0.5)2O were considered but they were unstable. When the atomic positions and unit-cell parameters were allowed to relax at each given volume, theI4/mmmstructure would destroy.) The zero-pressure bulk modulus (K0) of (FexNi1−x)2O decreases with the Ni content [see Supplementary...

The bulk modulus is also evaluated for MgO in the temperature range 300 - 200 K and down to a compression of V/V0 = 0.6 using an expression based on the Chopelas-Boehler approximation. The results obtained agree well with the ab-initio values determined by Isaak et al. 展开 ...
