The Rare Earths Solvent Extraction written by Xu and Yuan Cheng-ye has been awarded the first-class prize of the State Excellent Technical Books Awards.

Mr. Xu presented the"theory of rare earth extraction in series" after ten years of research for rare earth extraction separation process.He together with Prof. Li Biao-guo and Prof. Yan Chun-hua have spread the application of this technology to main rare earth factories in China and have helped to create hundreds of million economical and social benefit for the country.This research fruit has been awarded the third-class prize of the State Natural Science Awards, the third-class prize of the State Technology Advancement Awards and the first-class prize of the State Education Council Technology Advancement Awards.His research on chemical bond theory, quantivalence theory, the structure rule of atom cluster and the electronical structure of rare earth compound has been awarded the second-class prize of the State Natural Science Awards and the first Heliangheli Technology Advancement Awards in 1994.His work has been highly recognized by the people in this industry at home and abroad.He has assumed the president of international science conference and has been invited to report at international conferences for several times.In 1987, he assumed JSPS Senior Research Fellow and gave lectures at Tokyo University, Kyoto University and molecular science institute in Japan.During 1989 to 1995, he assumed the president of Asia Chemistry League.
