PIEZO INTEGRATE 15F-3, No.65, Gaotie 7th Rd., Zhubei City, Hsinchu County, 302058, Taiwan(ROC)

Description: This invention belongs to the field of piezoelectric material technology and discloses a high-sensitivity piezoelectric ceramic material, its corresponding sensor, preparation method, and applications. The ceramic material is composed of lead tetroxide (Pb₃O₄), strontium carbonate (SrCO₃), zirconium dioxide (ZrO₂), titanium dioxide (TiO₂), magnesium carbonate (MgCO₃), niobium pentoxide (Nb₂O₅), nickel oxide (NiO), zinc oxide (ZnO), cerium oxide (CeO₂), and lithium carbonate (Li₂CO₃). The chemical formula of the piezoelectric ceramic is: {(Pb, Sr)(ZrxTi₁₋ₓ)}{(Pb, Sr)(Mg₀.₃Nb₀.₇)}{(Pb, Sr)(Ni₀.₂₅Nb₀.₇₅)}{(Pb, Sr)(Zn₀.₂Nb₀.₈)}Ce₀.₁Li₀.₅ By carefully controlling the molar ratios of the raw materials, the resulting ceramic exhibits a high dielectric constant and piezoelectric coefficient, significantly enhancing material sensitivity. It is particularly suitable for use in hydrophones, ultrasonic flaw detectors, and other high-sensitivity acoustic applications. http://www.piezoig.com/hot_519588.html Patent Title: High-Sensitivity Piezoelectric Ceramic Material, Sensor, and Its Preparation Method and Applications (CN202510044041.9) 2025-07-17 2026-07-17
