Abstract
Crystals of R2SiO5, R2Si2O7, rare earth apatites, and square-faceted rare earth aluminium garnets containing silicon have been grown from fluxed melts. Silicon was provided in two ways: by vapour transport of a siliceous vapour species which diffused into the melts (“vapour-flux” method), and by including SiO2 in the initial mixtures. The results of these two methods are compared.
The materials have been characterized by X-ray diffraction and, in some cases, by EPMA. Powder pattern data for some of the rare earth apatites are included.
