Abstract
A series of synthetic garnets solid solutions is compositions between Y3Al2Al3O12 (Y-Al garnet) (YAG) and Ca3Cr2Si3O12 (uvarovite) was synth esized using the sol-gel method. The expected general formula is (CaxY 1-x)3 (CrxAl-x)2 (SixAl1-x)3O12 where x = 0 to x = 1. The cation distr ibution in dodecahedral, octahedral and tetrahedral sites and bond dis tances in these synthetic garnets were determined using the Rietveld m ethod. It shows the incomplete substitution in small sites. The smalle r site the smaller substitution there is.
