Comments on the paper “Structure, electric and dielectric properties of PbFe1/3Ti1/3W1/3O3 single perovskite compound” by P.G.R. Achary, R.N.P. Choudhary, S.K. Parida, published in Processing and Application of Ceramics 14 (2020) 146-153

Abstract

My comments concern the errors in the crystallographic part and possible misconduct of the authors of the commented paper regarding their usage of the same SEM image in different subsequent works. Moreover, the true chemical composition of the studied sample is questionable since the authors claim different systems for the same SEM micrograph in five different papers mentioned here.
