80s of last century, with the development of China's electronics industry and the needs of civilian products, household appliances, ceramic filters and ceramic resonators on the rapid increase in demand, 999 Jingdezhen in Jiangxi Province and Shanghai Radio Factory at the same time the introduction of Japan Murata piezoelectric ceramic frequency Component production line, opened the piezoelectric ceramics products from China to civilian production of large quantities of prologue. Through the exploration and digestion of Japan's advanced materials and process of introduction of the line, many small and medium-sized piezoelectric ceramic manufacturers have been rapid development, such as Zhejiang Jia Kang Electronics (former Jiaxing pottery plant), Jiangsu Jiang Jia Electronics, Wuxi Bao Tong Electronics, Suzhou Jie Jia Electronics. Jiakang electronics was the flagship product is the piezoelectric ceramic buzzer, the monthly output of 10 million, through the introduction of advanced technology lines, digestion, absorption and improvement, and soon became the largest output, the most complete variety of high-frequency Device manufacturers, piezoelectric ceramic devices by 2007 reached 715 million. Jiangsu Jiang Jia Electronics started producing a small amount of multi-chip ceramic filters, has now developed into the largest manufacturer of medium-frequency ceramic filters, to 2007 annual output has reached 467 million.

Great progress has been made in ceramic materials

Review of the development of piezoelectric ceramics industry in our country, only 20 years ago, only Shandong University, Tsinghua University, South China Institute of Technology, Tianjin University, Sichuan University, Shanghai Science and Technology University and several other universities have piezoelectric materials and applications of professional, Shanghai Silicate Research The CLP Research Institute No. 7 and the 26th Research Institute and other built piezoelectric ceramics and applied research laboratory, the manufacturer only Shandong Zibo radio ceramics factory, the main project carried out mostly with military products. Involving civilian products only mass-produced piezoelectric ceramic buzzer and igniter, a small amount for the post and telecommunications multi-chip ceramic filters, mechanical filters, acoustic and ultrasonic acoustic piezoelectric ceramic transducers.

In order to meet the different requirements of various types of piezoelectric devices on material properties, materials researchers extensively studied the modification of additives and developed a large number of high-performance piezoelectric ceramic materials.
