Impact of two-step calcination on microstructure, phase, electronic, and dielectric properties of KCa2Nb3O10 bulk layered perovskite
Autor: Jeong-Yeon Kim, Jong-Chan Lim, Sang-il Kim, Seong-Mee Hwang, Weon-Ho Shin, Heesun Yang, Kyu Hyoung Lee, Hyun-Sik Kim
Publikováno v: Journal of Asian Ceramic Societies, Vol 11, Iss 1, Pp 188-196 (2023)
ABSTRACTThe effects of varying calcination temperature, K content, and the number of calcination steps in the dielectric performance of KCa2Nb3O10 synthesized via solid-state reaction are investigated. Adding an extra calcination step at 500°C follo
