Piezo rings ceramic materials and applications:

The development of China's dielectric field is the rapid development of the power industry and the corresponding electrician manufacturing industry since the formulation and implementation of the first five-year plan in 1952. 

These schools, institutes and institutes first carried out researches on dielectric properties in our country and Personnel training, and opened the "dielectric physics", "dielectric chemistry" and other key professional courses, Xi'an Jiaotong University than Shanghai Jiaotong University, Harbin Institute of Technology and other institutions for our country trained thousands of insulation dielectric professionals, and promote our project Dielectric development. In the early 1980s, China Electrotechnical Society also established a professional dielectric engineering committee.
