Methods of extrusion are widely used in technology of thermoelectric (TE) materials manufacturing with high strength and good TE properties at temperatures above 200 K. The method of extrusion of Bi - Sb single crystals in the liquid environment under high hydrostatic pressure is considered. The construction of experimental equipment is presented. It was shown that presented method of extrusion allows preparing of polycrystalline material with high TE and improved strength properties at temperatures below 180 K.

Diffusion Coalescence

The effect of high hydrostatic pressure on the relaxation of the electrical resistivity at room temperature of oxygen-nonstoichiometric [Formula: see text] (Re = Y, Ho) single crystals is investigated. The application of hydrostatic pressure has been revealed to significantly intensify the process of diffusion coalescence in the oxygen subsystem. At the same time, the intensity of the redistribution of labile oxygen is significantly changed when yttrium is replaced by holmium.

Abstract This paper describes measurements of the dielectric constant and of the conductivity on pure and doped ice single crystals subjected to hydrostatic pressure. The dopants used were NH3 (c NH3 ≈ 5 × 10-5 to 1.2 × 10-4 mol/1) or HF (c HF = 5 × 10-6 and 5 × 10-4 mol/1). The pressure and temperature ranges covered were 1 to 1 500 bar and — 15 to 60°C. The activation volumes for the orientational and the ionic contribution to the conductivity could be determined. A definitive interpretation is not possible because many questions concerning the formation of the defects are still open, hi addition to the main subject, some new data from conductivity measurements on NH3-doped single crystals at atmospheric pressure are presented.
