ZnO is most widely and most attractive element in today’s research. ZnO powder is not available naturally. The ZnO powder was prepared by different methods. Here in this paper the preparation of powder was discussed. The powder was prepared by high temperature sol gel combustion method. Here in this study selected temperature was 500 0C ± 10 0C. to form the pure ZnO powder the synthesized powder was sintered at 6500C ± 10 0C. After sintering the white ZnO powder was formed with amorous in nature.This method was easy and high yield. The powder was characterized by using XRD and SEM. From XRD grain size was calculated. Using SEM the particle size, specific surface area, surface roughness and the surface morphology was studied.

Lead-free piezoelectric ceramics (1-x)Na0.5Bi0.5TiO3-xBaTiO3(x=0.04, 0.06, 0.08) was synthesized via sol–gel combustion method. Structural analysis was performed by using X-ray diffraction (XRD). The structural morphology of the nanoparticles was studied using scanning electron microscopy (SEM). The ceramics show a rhombohedral-tetragonal morphotropic phase boundary (MPB) in the range of x =0.04-0.08, which makes ceramics having superior dielectric and piezoelectric properties. There is a decrease of the grain size with increasing BT concentration, suggesting that dissolving BT into NBT inhibits the grain growth. And the multi-peak fitting result shows lattice constants of NBT have increased with the BT doped into NBT. Belong to the ionic polarization relaxation type, the low temperature dielectric anomalous peak shift towards a high temperature and the high temperature dielectric anomalous peak shift towards a lower temperature showed by the dielectric-temperature spectrum. Dielectric-temperature spectrum further determines that (1-x)NBT-xBT ceramics are relaxation ferroelectrics, and join BT makes the Curie temperature decreasing about 21 to 24°C. High piezoelectric properties with d33=148pC/N are observed in NBT-BT0.06.

In this paper, low temperature, economical sol–gel combustion method was adopted to synthesize wollastonite ceramic. Calcium nitrate tetrahydrate and tetraethyl orthosilicate were taken as source for Ca and Si, while citric acid and nitric acid were used as chelating/combustion agents. The yielded powder calcined at 600[Formula: see text]C for 4 h was characterized by FTIR, XRD and SEM techniques. Results showed that the citrate combustion method was the most efficient method to prepare wollastonite at low temperature. Moreover, in vitro bioactivity test performed in simulated body fluid (SBF) showed good bioactivity of synthesized wollastonite ceramics.
