In 2002, he published an article in the internationally famous magazine Nature, which fundamentally solved the interaction between phase transformation and grain growth of silicon nitride, thus realizing the random adjustability of the properties of silicon nitride-based ceramics. It is the first in the world to adopt fast and efficient discharge plasma sintering technology to prepare various transparent ceramic materials with first-class properties. Among them, the linear transmittance of transparent alumina ceramics reaches 64%, which is still the highest in the world. Invited to be the chairman of transparent ceramics branch of 201kloc-0/annual meeting of European ceramic society. Nano-barium carbonate and lead zirconate titanate ceramic materials were successfully prepared, and spark plasma sintering technology was proposed for the first time in the world to prepare ceramic materials with grain size below 100 nm, which provided a solid theoretical basis for the grain boundary design and final realization of nano-ferroelectrics. The paper on fully dense nano-structured BaTiO3 ceramics has been cited by him for more than 160 times in six years, which is the most cited paper in the field of nano-ferroelectric materials in recent years. The working principle and defect control mechanism of discharge plasma technology are put forward, which is an early pioneer in the research of discharge plasma sintering technology in Europe. Three published articles with more than 100 citations are all about the application of this technology in different materials, and have been invited to give special reports at international academic institutions and conferences for many times, which have been widely recognized worldwide. Directed ceramic research projects in Stockholm University and Royal Institute of Technology, Sweden, and trained 3 doctoral students and 4 postdoctoral students, master's and undergraduate programs 10. Since 2008, he has independently undertaken the undergraduate and postgraduate teaching tasks of ceramic courses in the Department of Materials Science and Engineering of the Royal Swedish Institute of Technology. It has undertaken a number of projects such as the Sixth Framework Dental Ceramics Project of the European Union, and successfully provided technical solutions for dental ceramics based on alumina and zirconia for enterprises, which won the highest evaluation among all sub-projects.
