수중청음기 응용을 위한 다공질 PZT 세라믹스의 압전특성
Piezoelectric properties of porous PZT ceramics for hydrophone Applications
초록
PZT powders were prepared by the molten salt synthesis method. The porous PZT ceramics were made from a mixture of PZT and polyvinylalcohol(PVA) by BURPS(Burnout Plastic Sphere) technique. The porous PZT bodies were fabricated from the green compacts with various amounts of PVA spheres. The piezoelectric coefficient d
