The Worst Advices We've Heard For Piezoelectric Ceramics
PZT-4 piezoelectric ceramic material modification is researching, piezoelectric ceramic is a kind of functional material to achieve the conversion of mechanical energy and electrical energy,
piezo ceramic ring plate datasheet is widely used in the field of electronics and microelectronics, which is an important, highly competitive international high-tech materials. At present, the lead-based piezoelectric ceramics
piezoelectric pressure sensor is represented by Pb (Zr, Ti) O3 dominate in this field. PZT-4 type piezoelectric ceramic material referred to as PZT-4 type material,it is an excellent transceiver material, ceramic speakers, underwater acoustic transducers, fish detectors, piezoelectric accelerometer, ultrasonic cleaning machine ,so it has a higher application. At present, the demand of
piezo ceramic plate actuator PZT-4 type material is also different in many aspects. Therefore, it is necessary to modify the material to meet the different market demands.The commonly is used modification are using different additives, additives of P5 material piezo ceramic are divided into soft additives, hard additives and other additives, the
electrical piezo ceramic ring of study will be soft additives and rigid additives PZT-4-based materials were modified study . In this experiment, two different additives Bi2O3 and Fe2O3 were used to modify the
PZT 5 for beauty device to prepare samples. The purity of the main raw materials is used for Pb3O4 ≥ 97.5%, ZrO2 ≥ 98%, TiO2 ≥ 99%, Fe2O3 ≥ 99.5%, Bi2O3 ≥ 99%, where the content of the additive Bi2O3 is 0.3%, 0.6%, 0.9% 1.2%, Fe2O3 content (weight ratio) were 0.2%, 0.4%, 0.6%, 0.8%. Using orthogonal test methods to determine the various formulations. According to different formulations, the ingredients were ball milled for 8 hours, then calcined at 850 ℃ in air for 2 hours and then milled for 24 hours again. After drying, polyvinyl alcohol granulation was carried out. Under the pressure of 1.8 t / cm2 Forming, processing into φ20 × 1 wafers, infiltrating silver at 700 ℃, polarization of 3.5 kV / mm, measuring after placing for 10 days at room temperature for data analysis.
