Control of the degree of compositional ordering of Pb2YbMO6(M – Nb, Ta) perovskites by means of mechanical activation

It has been found out that compositional ordering degree of the Yb3+ and M5+ (M – Nb, Ta) ions in Pb2YbМO6 ceramics and, correspondingly, both temperature and diffusion of antiferroelectric phase transition can be varied within a wide range by means of high-energy mechanical activation. In particular, disordered modifications of Pb2YbМO6 (M – Nb, Ta) were obtained without using any additives for the first...
