Dependence of Pyroelectric Properties of La0.03Sr0.255Ba0.7Nb2-yTiyO(6-y/2) Ceramic on Electric Field, Grain Refinement and Ti/Nb Crystallite Sizes

The pyroelectric properties of La0.03Sr0.255Ba0.7Nb2-yTiyO(6-y/2) (LSBNT) ceramic pellets using several Ti/Nb ratios sintered at 1250 degrees C for 5 h were investigated. The samples were subjected to several values of electric fields in order to obtain the optimum electric field strength. The pyroe...
