Relaxer ferroelectric monocrystal for ultrasonic converter

摘要

(57) Abstract It showed the phase change of electric field being induced at the electric field level which is larger than 10Ec (as for Ec coercivity field), with the high electronic mechanical join where 001 crystal of orientation of the lead niobate spelter - titanic acid lead solid solution (from 0 5mole% titanic acid lead) exceeds 85%, high sensitivity/it could obtain the converter property of big band width increase of converter Drive voltage and decrease of production degradation, and with the electronic mechanical join whose is high up to 92%. Lead niobate magnesium, 001 also crystal of orientation of the - titanic acid lead solid solution (from 20 the titanic acid lead of 50mole%) exceeds 85% and shows the electronic mechanical join whose is high up to 94%, it is possible to form in the converter which shows high sensitivity and large band width.
