摘要：

Synthesis and characterization of some crystalline garnets by sol-gel techniques is described. The effects of methanol, dimetyl sulfoxide (DMSO), CH2Cl2 and toluene solvents on gelation of TEOS are considered. Multicomponent gel formation in systems with stoichiometries 3CaO . Cr2O3 . 3SiO2 and 3CaO . Al2O3 . 3SiO2 was studied using DMSO, a polar solvent, and toluene, an apolar solvent. The dried gel was thermally treated and the powder was characterized by X-ray diffraction, differential thermal analysis/thermogravimetric analysis and scanning electron microscopy.
