Pre-mullite powder has been synthesized by sol-gel process followed by calcination. Aluminium nitrate and tetraethyl ortosilicate (TEOS) were used as the starting materials. X-ray diffraction (XRD) analysis showed that calcined pre-mullite powder is completely amorphous. The powders were wet milled

LaCoO 3 -based materials are studied because they exhibit interesting, electrical, magnetic and catalytic properties. In this contribution, LaCoO 3 powders were synthesized by sol-gel method in aqueous medium starting from metal nitrates or acetates, and citric acid as the chelating agent at room te

## Abstract ZnO:Al ceramics (Zn:Al, 0.95:0.05) were prepared by using sol‐gel derived nanocrystalline powders. XRD patterns of the doped ceramics revealed the existence of both zincite (JCPDS 36‐1451) and gahnite (JCPDS 5‐0669) phases. Gahnite phase (ZnAl~2~O~4~) was segregated along the ZnO grain
