Description
Peculiarities of electret state in La4Ti4-x(Se,Nb)xO14 base oxide ceramics are considered. Possibility to obtain residual polarization is determined. Electret ceramics is pointed out to be of rather high time and thermal stability of surface potential. Incrased ability of electretization results from existence of additional centres of capture of charge carries within interlayer boundaries
