Compressibility of boron subphosphide B12P2 has been studied under quasi-hydrostatic conditions up to 26 GPa and 2600 K using laser-heated diamond anvil cell and angle-dispersive synchrotron X-ray diffraction. 300-K data fit yields the values of bulk modulus B0 = 192(11) GPa and its first pressure derivative B0' = 5.5(12). At ambient pressure the thermal expansion is quasi-linear up to 1300 K with average volume expansion coefficient {\alpha} = 17.4(1) 10-6 K-1. The whole set of experimental p-V-T data is well described by the Anderson-Gr\"uneisen model with {\delta}T = 6

“…X-ray patterns were collected on a Canberra solid state Ge-detector with fixed Bragg angle 2qZ 9.260(3)8. The temperature of the high-pressure cell was controlled by a Eurotherm PID regulator within 2 K. Pressures at different temperatures were calculated from lattice parameters of hBN using its thermoelastic equation of state [18]. The details of experiments and high-pressure setup have been described earlier [18][19][20].…”

X-ray diffraction with synchrotron radiation has been used for the first time to study the formation of Mg x Zn 1Kx O (MZO) (0.33%x%0.83) solid solutions with rock salt structure at pressures up to 4.4 GPa and temperatures up to 1500 K. The chemical reaction between MgO and ZnO and a subsequent phase transformation of wurtzite solid solution (w-MZO) into rock salt one (rs-MZO) was observed at a stepwise heating at various pressures. The lattice parameters of rs-MZO solid solutions of different stoichiometries have been in situ measured at high pressures and temperatures. Unlike pure ZnO, the quenching of the reaction mixtures resulted in the formation of stabile MZO solid solutions with the rock salt structure. The phase diagram of the MgO-ZnO system at 4.4 GPa has been proposed based on the experimental data. q

“…The correction for the pressure effect on the thermocouple emf was made using the data of Getting and Kennedy [6]. Pressures at different temperatures were evaluated from the lattice parameters of highly ordered graphite-like hexagonal boron nitride using the p-V-T equation of state of hBN [4]. The pressure variations with increasing temperature were found not to exceed G200 MPa in the 2-mm central part of the cell over the experimental temperature range.…”

The lattice parameters of Al 3 BC have been measured up to 5 GPa at ambient temperature using energy-dispersive X-ray powder diffraction with synchrotron radiation. A fit to the experimental p-V data using Birch-Murnaghan equation of state gives values of the Al 3 BC bulk modulus 116(4) GPa and its first pressure derivative 9(2). In the 1.6-4.8 GPa range at temperatures above 1700 K Al 3 BC undergoes incongruent melting that results in the formation of Al 3 BC 3 , AlB 2 and liquid aluminum. q
