The Bi-Te-I system has been studied by differential thermal analysis, x-ray diffraction, and emf measurements in the temperature range 300–400 K using concentration cells of the type (?)Bi(s) | glycerol + KI + BiI3 | Bi-Te-I(s)(+). The results have been used to construct the 300-K section of the Bi-Te-I phase diagram. The existence of the ternary compounds BiTeI, Bi2TeI, and Bi4TeI1.25 has been confirmed, and the position of the phase fields involving these compounds has been accurately determined. Using emf data, we have evaluated the partial thermodynamic functions (Δ\(\bar G\), Δ\(\bar H\), and Δ\(\bar S\)) of the bismuth in the alloys studied, the standard thermodynamic functions of formation of the ternary compounds, and their standard entropies. 相似文献

The electrical properties of electrodeposited CdTe thin films have been studied. The temperature-dependent electrical conductivity data obtained have been used to determine the conductivity type and semiconductor parameters (E g, B, and α) of the films. 相似文献

We study the influence of salts of alkylphenol sulfonic acid on the corrosion of St3 steel in a 0.1 N HCl–kerosene system.
All salts have inhibiting properties beginning with a concentration of 25 mg/liter and, in some cases, completely inhibit
corrosion. It is shown that the protective effect increases with temperature. Within the range of concentrations of the inhibitor
25–200 mg/liter, the activation energy of corrosion becomes 5–6 times higher. Thus, the investigated compounds inhibit corrosion
of St3 steel as a result of chemical adsorption.

The phonon heat conductivity k
ph in Bi1 − x
Sb
x
(x = 0.04–0.12) alloys is investigated in the temperature range of 6–60 K. The results are compared with the theory of solids
at low temperatures, and the basic sources of phonon scattering are revealed. It is shown that phonon scattering at local
mass changes dominates over other sources. The dependences of k
ph on composition are considered at temperatures of 60 and 90 K, and it is found that the normal N processes substantially affect the phonon scattering under these conditions. The donor-impurity effect on heat conductivity
of Bi0.88Sb0.12 is considered, and the heat resistance caused by the phonon scattering at impurity centers is singled out. 相似文献

The contours of the bands corresponding to totally symmetrical vibration ν1(A
1) and vibration overtone ν2(E) of the perchlorate ion in molten lithium perchlorate are studied. Vibrational dephasing is found to be the main factor of
the broadening of isotropic spectral bands. The dephasing of vibrations in an LiClO4 melt is shown to obey a Gaussian-Markovian mechanism. 相似文献

The influence of gamma radiation on the TSD spectra of polyolefines and their mixtures has been studied. It is established that the TSD spectrum maximum position depends on the gamma irradiation and the concentration ratio of the components of the polyolefine mixtures. 相似文献
