Comments on the errors in paper “Impact of KBiTiO3 in optical and ferroelectric behavior of NaNbO3 solid solution” by S.K. Mohanty et al., and published in J. Mater. Sci.: Mater. Electron. 34 (2023) 2126

摘要

My comments concern the uncertainties in the crystallographic part of the commented paper. The correct crystal structure should be described as NaNbO3:K,Bi,Ti instead of solid solution proposed by authors and described as 0.075(K0.5Bi0.5TiO3)–0.925(NaNbO3). Moreover, the studied sample has no ferroelectric properties; the P–E loop is of “banana”-type, only.
