Effects of Atmospheric Powder on Dielectric, Piezoelectric, and Ferroelectric Properties of NaSr 2 Nb 5 O 15 Ceramics
Source abstract
Abstract
NaSr 2 Nb 5 O 15 piezoelectric ceramics were sintered at different temperatures with or without atmospheric powder. The effects of atmospheric powder and sintering temperature on the dielectric, piezoelectric, and ferroelectric properties of the ceramics were analyzed. According to the modified Curie–Weiss law, we know that all these ceramics show an intermediate relaxor‐like behavior between the normal and ideal relaxor ferroelectrics. Atmospheric powder affects significantly the properties of ceramics because the ceramics sintered without atmospheric powder lose lots of sodium. Furthermore, sintering temperature also significantly affects the properties of ceramics because the relative density of ceramics is enhanced when sintering temperature is increased.
