| Abstract: | Crystallization of monticellite CaMgSiO4 from melt by the floating-zone technique was studied at different compositions of feed rods. The compositions of rapidly cooled melts and different regions of grown crystals were investigated by the X-ray phase and microprobe analyses. The inclusions of secondary phases were identified. The range of most promising compositions of the charge for technology of growing large high-quality crystals is established. The mathematical model of the changes in the melt composition during monticellite crystallization is constructed. |
