High sintering activity NaNbO3 powder synthesis via the polyacrylamide gel method and fabrication of a NaNbO3 ceramic at lower temperature
NaNbO3 powder was synthesized via the polyacrylamide gel method, growth behaviors and associated morphology were discussed. The calcined NaNbO3 powder at 565 °C possess cubic and long columnar morphology which are NaNbO3 and Na/Nb/F or Na/Nb/F/O compounds, respectively. According to XRD and SEM, as...
