Academic Achievements:

1. Research Achievements:

(1) He put forward a new ceramic forming technology, namely colloidal injection forming of ceramics, and got 8 state patents for it. He proposed and achieved the academic thought about the injection molding of water-based and non-plastic slurry, which hold 13 science and technology achievement testimonials issued by Ministry of Education and Sci-Tech Department of Hebei Province. Many achievements had reached the international advanced and the leading level.

(2) He proposed a novel method about the preparation of green body in the process of colloidal forming, which can avoid the inner stress. He indicated that although the green body with uniform density can be obtained by colloidal forming, many inner stress were produced during the transformation from liquid to solid, and the stress would be developing, inheriting and variating in the course of drying, de-bindering, sintering and machining. The technique how to overcome the inner stress would become the future development direction of colloidal forming of ceramics. Furthermore, there are 2 state patents for invention and 1 National Natural Science Foundation of China for the program to be gotten.

(3) The first colloidal injection molding and industrialization original machine were prepared successfully in the world. 2 state patents for invention were got. 2 science and technology achievement testimonials issued by Ministry of Education in China. So far, an industrialization base with more than 9000 square meters was constructed.

(4) He revealed the formation mechanism of cracks which developed during the transformation from liquid to solid of the ceramic concentrated suspension for the first time, and put forward two proposals to avoid cracks. He also got 2 state patents for invention.

(5) He invented a novel molding technology, which can make the suspension mix uniformly and quickly, as well as the solidification controllable. 1 state patent of invention was got at the same time. This forming process of ceramics could be used to divide ceramic suspension into two or more components, which can be kept in storage for a long time and without solidification. However, when those components were mixed quickly and uniformly, they would react and solidify rapidly. The method, which can be used universally, is a breakthrough in the wake of novel colloidal forming of ceramics and also lays a solid foundation for the establishment of production lines.

(6) He invented a preparation method and equipment for the high-performance ceramic microbeads. The entire production line has all the intellectual property rights and 3 science and technology achievement testimonials issued Ministry of Education and Sci-Tech Department of Hebei. In 2005, this production line for ceramic microbeads was bought by Saint-Gobain group.

(7) He invented and developed the testing equipment for gel point. It can test the relationship between time and temperature during the gel reaction online and provides a means to research the gel reaction kinetics. He has published more than 10 papers and got 1 state invention patent for it.

(8) He invented new dielectric materials of ceramic composites, which can reduce the starting voltage from 8000V to 1000V, increase the ozone production for more than 10 times, and lower the manufacturing costs significantly. 2 state patents for invention were got for it and many ozone generators had been prepared successfully.

(9) Zirconia ceramic microbeads were applied to the pen industry. The writing life of gel-pen was prolonged for more than 5 times. The program also became the key project of the China Pen Industry Association for the Eleventh Five-Year Plan.

(10) A new way to prepare micro-hollow spheres using solids waste such as coal gangues and fly ash by advanced ceramic technology was developed. Both state patent for invention and a PCT patent were applied.
