"Research on the Preparation and Application of High-Purity Two-Dimensional Nanoserite Materials and Inorganic UV Shield" project passed the provincial expert identification

The "Preparation and Application Research of High-purity Two-Dimensional Nanoserite Materials and Inorganic UV Shield" project, jointly completed by Chuzhou Grea Mining Co., Ltd. and Nanjing University of Technology, passed the provincial appraisal organized by the Anhui Provincial Department of Science and Technology on April 28, 2007. "The method of preparing high-purity two-dimensional nanoserica in the wet-stripping system by combining agent intercalation and microwave oscillation, the process of repairing the smoothness of mica surface with columnar medium, the use of high-purity two-dimensional nanoserica to prepare inorganic ultraviolet shielding agents, and the performance of schist-type mica materials with ultraviolet absorption rate of 90%" are both firsts at home and abroad. The results of this project have been rated by experts to reach the international advanced level.
