All rights reserved. In this study, transparent glass-ceramics from potassium sodium niobate (KNN)-silicate glass system doped with erbium oxide (Er2O3) were successfully prepared by incorporation method. KNN was added in glass batches as heterogeneous nucleating agent. The KNN powder was mixed with SiO2and Er2O3dopant with KNN and Er2O3content varied between 70-80 and 0.5-1.0 mol%, respectively. Each batch was subsequently melted at 1300°C 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. XRD results showed that the prepared glass ceramics contained crystals of KNN solid solution. In contrary, dielectric constant (εr) and dielectric loss (tan δ) were found to increase with increasing heat treatment temperature. Additionally, optical properties such as absorbance and energy band gap have been investigated. 2018-09-04T10:14:29Z 2018-09-04T10:14:29Z 2015-09-01 Journal 00255408 2-s2.0-84939936730 10.1016/j.materresbull.2015.02.004 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84939936730&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/54482 |
