Dependence of pyroelectric properties of La0.03Sr0.255Ba0.7Nb2-yTiyO(6-y/2) ceramic on electric field, grain size and Ti/Nb crystallite sizes

Dependence of pyroelectric properties of La0.03Sr0.255Ba0.7Nb2-yTiyO(6-y/2) ceramic on electric field, grain size 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¡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 pyroelectric...
