Диэлектрические свойства сегнетоэлектрических композитов на основе KNO3-BaTiO3 и KNO3-LiNbO3

open access: yesИзвестия Российского государственного педагогического университета им. А.И. Герцена, 2011
The influence of barium titanate and lithium niobate (2-30 microns) particles on the ferroelectric properties of potassium nitrate in the composites (KNO3)1-x(BaTiO3)x and (KNO3)1-x(LiNbO3)x for x from 0 to 0.5 is studied. It is shown that there is an interaction between individual components in ferroelectric composites, which can lead to changes in ...
