Recently, the American Ceramic Society Online presented various international ceramic awards in 2020, and Professor Li Fei and Xu Zhuo of Xi'an Jiaotong University won the Ross coffin Purdy award. After 35 years, Xi'an Jiaotong University once again won the top of international ceramics!

The American Ceramic Society established the Ross coffin Purdy award in 1949 to award the authors who have made the most valuable contributions in the academic literature published in the field of ceramics in the first two years. Only one research achievement is awarded each year in the world.

Professor Xu Zhuo and Professor Li Fei, Key Laboratory of electronic ceramics and devices, Ministry of education, Xi'an Jiaotong University, have long been engaged in the research of piezoelectric materials, and have carried out a lot of scientific research on the origin and high performance of relaxor ferroelectric single crystals. In 1985, academician Yao Xi won the award for his research work on "the influence of grain piezoelectric resonance of lithium niobate ceramics on its dielectric spectrum". After 35 years, Xi'an Jiaotong University won the international ceramic award again, which showed the profound accumulation and inheritance of Xi'an Jiaotong University in the field of ferroelectric and piezoelectric materials.

In 2020, the award-winning achievement of Ross coffin Purdy award is "design of ferroelectric ceramic materials with high-voltage electric effect" by Professor Xu Zhuo and Li Fei's team. This achievement has made a breakthrough in the design and synthesis of high-performance piezoelectric ceramics. By introducing local structural disorder, Pb (mg) doped with rare earth element SM is synthesized for the first time, The piezoelectric coefficient of NB) o3-pbitio3 piezoelectric ceramics is up to 1500 PC / N, which is twice that of commercial soft piezoelectric ceramics. This achievement was published in the Journal of nature materials in 2018, and then introduced by news & views of Nature Materials Journal, and published in science journal in 2019.
