How Will Piezoelectric Ceramics Be In The Future

About piezoelectric ceramics ,it solves the problem is to achieve high power, high efficiency, high reliability in the future to , therefore, the need for further study of the new piezoelectric materials and structures, resonance piezoelectric sensor gets a greater boost ratio and higher conversion efficiency. If you do not consider the size of the piezoelectric ceramics transformer, increase power, used in negative ion generator and other electrical equipment QRS. Piezoelectric ceramic sensors tube has proved that the use of technology to produce multi-type piezoelectric ceramic transformers to meet the market requirements of the notebook with backlight. Low-temperature sintering technology more and more attention. Low-temperature sintering can not only reduce the volatility, thus hemisphere piezoelectric ceramic transducer is ensuring the chemical composition of components of the accuracy, and the history will greatly reduce the pollution of the environment in the China's Tsinghua University, a series of glass frit as an additive, so that the sintering temperature of porcelain from the original decrease, while piezoceramic transducer ring effects is the sintered porcelain piezoelectric properties and stability than the original performance of the porcelain not only did not reduce, but also ring shape piezo ceramic pzt 8 is increased. This porcelain has been successfully used to make high step-up ratio of monolithic ceramic transformers, AC no-load step-up ratio.In addition, with the improvement of people's awareness of environmental protection, lead-based piezoelectric ceramics are being replaced by lead-free ring piezoelectric actuator transducer piezoelectric ceramics step by step. The research and application of lead-free piezoelectric ceramics have also become the hot spots currently developed. Which has developed a series of niobate-based ceramics, bismuth layered piezoelectric ceramics, titanate ceramics and a series of lead-free piezoelectric ceramics, the performance has been a great breakthrough. According to the "International Electronic Business" report, all electronic products are lead-free . And some countries have also legislated against the use of lead-containing piezoelectric ferroelectric materials. Therefore, from a development point of view, which is looking for an alternative .The lead-free piezoelectric ceramic material is a very necessary and urgent issue
