Dielectric properties and microstructural studies of Er<inf>2</inf>O<inf>3</inf>doped potassium sodium niobate silicate glass-ceramics
© 2018 Trans Tech Publications, Switzerland. In this work, electrical and structural properties of ferroelectric glasses and glass-ceramics from K0.5Na0.5NbO3-SiO2doped with 0.5-1.0 mol%Er2O3system have been investigated. The influent of Er2O3dopant was also compared with the original glass. The K0....

The influent of Er2O3dopant was also compared with the original glass. The K0.5Na0.5NbO3(KNN) powder was mixed with SiO2in composition of 75KNN-25SiO2and doped with Er2O3. Well-mixed powder was subsequently melted at 1300oC for 15 min in a platinum crucible using an electric furnace. The quenched glasses were then subjected to heat treatment at various temperatures for 4 h. From the study, KNN single phase in transparent glass was successfully prepared via incorporation method. The maximumrof about 360 at 10 kHz with a low tanδ of 0.07 could be obtained from the glass-ceramic sample of 75KNN–25SiO2doped 0.5 mol% Er2O3and heat treated at 600C. It can be seen that the higher percent of Er2O3can lower the dielectric loss of KNN glass-ceramics. This interesting value suggesting the opportunity of using them in electronic applications in the future. 2018-09-05T04:28:54Z 2018-09-05T04:28:54Z 2018-01-01 Book Series 10139826 2-s2.0-85046087804 10.4028/www.scientific.net/KEM.766.258 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85046087804&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/58704 |
