Opis

Papers from the Sixth All-Union Conference on Growth of Crystals comprise Volume 16 of this series. The articles were chosen with a view to more fully elucidate the basic problems of crystal growth as reflected in domestic and foreign reviews and in original studies. This volume consists of six parts. Part I is devoted to mechanisms of crystal growth that are important for production of materials with given properties. This part examines the temporal evolution of an inhomogeneous state and the array of semicellular and eutectic structures during microstructure formation, the effect of impurity on the nonequi- librium vacancy concentration in a growing crystal, and the role of soluble and insoluble impurities in the birth and growth of crystals. Part II deals with the synthesis and electrophysical properties of novel solid electrolytes that are promis- ing for practical use, analysis and correlation of the large amount of data on growth by the Bridgman-Stockbar- ger method of single crystals of fluorite phases far from stoichiometry, and the hydrothermal chemistry and growth of hexagonal germanium dioxide.
