Synthesis and characterization of cerate-zirconate ceramic powder prepared by supercritical fluids, sol-gel and sol-gel assisted supercritical fluids methods: a comparison study / Najwa 'Adni Ibarahim

TGA result showed that the thermal decomposition temperature for S2 was higher than SI and S3. The traces of carbonate residue and secondary phase were observed for both S2 and S3 powder due to the incomplete combustion of intermediate compounds. However, SI shown highly crystalline powder and its XRD peaks were matched to the standard BCZY compound (JCPDS card 89-2485). All the major peaks can be indexed to the index miller of (110), (111), (200), (210), (220) and (310). The particle size was in the range of 0.2 to 0.5 urn for the first group of agglomerat
