A series of synthetic garnets solid solutions with compositions between Y 3 Al 2 Al 3 O 12 (Y-Al garnet) (YAG) and Ca 3 Cr 2 Si 3 O 12 (uvarovite) was synthesized using the sol-gel method. The expected general formula is (Ca x Y 1-x ) 3 (Cr x Al 1-x ) 2 (Si x Al 1-x ) 3 O 12 where x=0 to x=1. The cation distribution in dodecahedral, octahedral and tetrahedral sites and bond distances in these synthetic garnets were determined using the Rietveld method. It shows the incomplete substitution in small sites. The smaller site the smaller substitution there is
