Head KOSMYNA MIRON BOGDANOVICH, Registration Date 20-03-2003 Organization Department of Optical and Constructional Crystals of STC <Institute for Single Crystals> popup.description2 Conducted were investigations on growing calcium-gallium-germanium garnet (CGGG) in which Ca3+ ions were partially substituted for Fe, Cr, V, Mn ions. Selected were growth conditions and grown were crystals of the following compositions: Са3Gа2-хFехGе3О12; Са3Gа2-x СrхGе3О12; Са3Gа2-x VхGе3О12, where x in the initial raw material varied from 0.01 to 0.1. It was found that at x<0.05 in the raw material growth of crystals has the same difficulties as when growing pure CGGG. Thus, the most principal effect on the growth process has evaporation of GeO2. Microscopically it was found that all crystals have a typical volume defect which passes through the center of the crystal and a noticeably pronounced striation across the crystal.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
