Piezoelectric ceramic disc Lead free Piezo ceramic disc The Co-Al Co-doped Barium Titanate Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company through repeated experiments. By Researching the influence of Co-Al Co-doping on the structure and properties of Barium Titanate-based piezoelectric ceramics, the formulation and preparation technology of Barium Titanate-based piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N), dielectric loss tgδ≤0.5% and mechanical coupling coefficient Kp≥0.34. Application: ultrasonic transducer Piezoelectric Ceramic Material: BaTiO3 (lead free) Piezoelectric elements technical data: Dimensions: diameter 36.83mm, thickness 13-16mm (according to the fequency 200KHz) Thickness Frequency Fr: 200KHz ± 4 KHz Frequency Bandwidth ΔF>8.5 KHz Re…
