- Application of Piezoelectric Ceramics in Mechanical SystemsSince the curie brothers discovered the piezoelectric effect of tourmaline in 1880, piezoelectric science has officially entered the stage of human science and technology civilization. Early theoretical research was mainly done by the curie brothers later. In 1881, the curie brothers verified the inBasics of Piezoelectric Ceramics November 30, 2018
- Analysis of piezoelectric ceramic performance parametersThe manufacture of excellent piezoelectric ceramic components usually requires requirements for the performance of piezoelectric ceramics. Because the performance of piezoelectric ceramics has a decisive influence on the quality of components. Therefore, to discuss and understand the components of pBasics of Piezoelectric Ceramics November 28, 2018
- Admittance characteristics of piezoelectric ceramicsThe admittance characteristics are further analyzed based on the obtained equivalent circuit diagram of the piezoelectric ceramics transducer. In order to simplify the derivation, it is assumed that the piezoelectric ceramic transducer has no electrical loss, that is, 0R=0, and the equivalent circuiBasics of Piezoelectric Ceramics November 28, 2018
- Application of Piezoelectric Ceramic Used in Ultrasonic Distance TransducerIn the past 20 years,piezoelectric crystal cost has developed rapidly at home and abroad. Due to their advantages of simple production, low cost and good stability, they have been widely used in the fields of electronics, light, heat and acoustics, and have a wide range. Ultrasonic transducers are mBasics of Piezoelectric Ceramics December 05, 2018
- sintering conditions of piezoelectric ceramics(2)The effect of pre-firing temperature. When the calcination temperature of piezo ceramic crystals is low, the particle size is fine but the difference is small, the accumulation in the green body is not tight, and the contact points are not much, which is unfavorable. When the calcination temperaturBasics of Piezoelectric Ceramics November 26, 2018
- sintering conditions of piezoelectric ceramicsThe sintering conditions of piezoelectric ceramics are mainly composed of four aspects: 1 heating rate; 2 highest sintering temperature; 3 holding time; 4 cooling rate and cooling mode. The general principle for the development of reasonable sintering conditions is to burn high-quality porcelain ( tBasics of Piezoelectric Ceramics November 25, 2018
- What’s the piezoelectric ceramic sinteringSintering is a process in which heat is used to transform a green body into a dense piezoelectric ceramics body having a certain microstructure. They are sintexring theory points and sintering process, consciously perform the sintering process, here briefly introduce the main points of sintering theBasics of Piezoelectric Ceramics November 25, 2018
- forming method of piezoelectric ceramic embryo (2)Granulation is a process in which a porcelain PZT material parameter is mixed with a binder to prepare coarser particles (about 20 mesh/inch) having good fluidity. This kind of granule is called a pellet to show the difference.1) The role of granulationSince the ground porcelain powder of sensitiveBasics of Piezoelectric Ceramics November 22, 2018
- forming method of piezoelectric ceramic embryoThere are many methods for forming ceramic embryo , such as pressure forming, plastic forming and slurry forming. Each type of forming method can be divided into several specific forming methods of Pzt ceramic disc. It can be selected according to the shape, specification and size of the product, buBasics of Piezoelectric Ceramics November 22, 2018
- manufacturing process of piezoelectric ceramic(1) The process method of piezoelectric ceramics is to use a ball mill (drum type, planetary type, agitating type and vibrating type ball mill), and add grinding balls (steel balls, agate balls, zirconium balls, etc.) and media (water, alcohol, etc.) to the raw materials. It is mechanical mixing orBasics of Piezoelectric Ceramics November 21, 2018
