A simple synthetic approach to BaZrS3, BaHfS3, and their solid solutions
Journal of the American Ceramic Society, Volume 107, Issue 2, Page 698-703, February 2024.Abstract A simple synthetic approach to BaZrS3, BaHfS3, and their solid solutions is presented and discussed here. The synthesis is performed under relatively mild conditions (T = 500°C) and is complete in a few hours. The reactants are powdered BaS, Me (Me: Zr, Hf) and S in a ratio 1:1:3, mixed and sealed under vacuum in borosilicate glass ampoules ...
