摘要
Garnet compounds A (3) (2+) B (2) (2+) C4+V (2) (5+) O-12 (A = Ca, Cd; B = Mg, Zn, Co, Ni, Cu, Mn, Cd; C = Ge, Si) (space group , Z = 8) have been prepared by solid-phase synthesis in air at 900-1250A degrees C. Most of these compounds melt incongruently or decompose in the solid phase. The isomorphic capacity of garnets and their homogeneity fields are discussed. The structures of Ca3Zn2GeV2O12 and Ca3Cu2GeV2O12 have been refined by the Rietveld method.
