Thermodynamic Functions of (InP)z(InAs),-, from 5 to 300 K Temperature dependence of the heat capacity of the solid solutions (InP),(InAs)l-, has been investigated over the temperature range from 5 to 300 K. Solid solution samples with z = 1; 0.8; 0.6; 0.4; 0.2; 0.1; 0 produced by means of crystallization from the melt the following annealing and diffusion in the powder a t temperature close to solidus have been studied. The absolute values of enthalpy H , entropy S, Gibbs free energy 2 as well as their deviations from the additive values have been obtained for the (InP),(InAs)l -z system from the analysis of the thermodynamic properties of the solid solutioiis of the 111-V compounds at low temperatures. The curves for the characteristic temperatures
BYAs p a r t of a systematic study on lattice dynamics of hexagonal metals /l/ this note reports on anisotropic atomic vibrations and the thermal expansion coefficient in titanium. Titanium is a polymorphous metal, below 1155 K it has a closepacked hexagonal structure and crystallizes into the magnesium-type lattice with an axial ratio of 1.587, i.e. the crystal is compressed along the c-axis. istics /2, 3/ and on the anisotropy of the thermal expansion coefficient /4 to 6/.
The effect of the additions of rare-earth elements Nd, Sm, Eu and Tb on the thermal conductivity of gadolinium-gallium garnets and besides the influence of the joint doping with Nd and Cr on the thermal conductivity of gadolinium-gallium and more compound gadolinium-scandium-gallium, gadolinium-calcium-magnesium-zirconium-gallium and yttrium-scandium-gallium garnets have been investigated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
