their flat response in a broad spectrum, no need for cooling accessories, relatively fast response and low cost compared with photodetector, and are applied to a wide range of applications such as nondestructive motion detection, IR/THz material analysis, gas/flame monitoring and laser measurement ...
PMN-32%PT crystals possess a very high piezoelectric properties. The electromechanical coupling factor for the transverse extension mode is k32 > (0.84–0.91) [42–44]. The Curie temperature for the PMN-32%PT crystals is 90 ◦C [44]. It allows using them in majority of NDT applications...
The molar fraction of PT varies in range (0.37 < x < 0.57). The composi- tion of the second section is 0.98(xPbTiO3–yPbZrO3–0.15PbMg1/3Nb2/3O3)–0.02PbGeO3. The molar fraction of PT varies in range (0.3 < x < 0.55). The molar fractions of PZ are related to the molar ...
