Solid State Ionics | 1992

The influence of the front of crystallization upon the phase content in RbAg4I5 bulk crystals grown in microgravity

A. S. Popov; I.Z. Kostadinov; M.D. Mateev; L.L. Regel; N.A. Baturin

Abstract The phase content in RbAg4I5 bulk crystals grown in microgravity was investigated by X-ray analysis, scanning electron microscope analysis and Raman spectra. A favorable effect of microgravity on the growth processes was demonstrated. The effect manifests itself in the better homogeneity of crystals and decrease of structural imperfection.


Solid State Ionics | 1992

An electrolytic cell prepared from RbAg4I5 crystals

A. S. Popov; I. Ivanov; A. Bahnev

Abstract The electrolytic cells are prepared from RbAg4I5 crystals grown in microgravity conditions and in analogous earth ones. A comparison is made between two kinds of electrolytic cells and the observed differences are related to the better quality of space crystals.
