In the p.esent study, the effect of La.dop.ng wa. investiga.ed on the structura., microstructura., dielectric, p.ezoelectric, a.d ferroelectric p.op.rties of the cera.ics. The results show tha., the tetra.ona. （sp.0}e group.p.mm） a.d rhombohedra. （sp.0}e group.R3c） p.a.es a.e observed to coexist in the sa.p.e a. x = 0.012. Microstructura. investiga.ions of a.l the sa.p.es revea. tha. La.dop.ng inhibits gra.n growth.

p.osp.orous is widely considered a. a. imp.rity in steels. Consequently, its role a. a. imp.rta.t a.loying element in iron could never be esta.lished.
