【Research Interests】(研究興趣)
(1)Semiconducting Ceramics: Obtained the dense BaTiO3 ceramics with the best resistance jumping in the world till this time using vapor doping method which was developed in 1997 by Dr Qi (the jumping almost reached greater than 8 orders’ degree).
半導體陶瓷:1997年得到了升阻比超過8個量級,溫度系數大于40%/0C的致密PTCR陶瓷材料,這是迄今為止致密陶瓷中,國內外最高水平(超過7個量級的致密的PTCR陶瓷是罕見的)。
(2)Dielectric Ceramics:High voltage BaTiO3 based capacitor materials: >4kv/mm(AC), dielectric constant>20000, meeting Y5V specifications. Media-low temperature BaTiO3-based X7R MLCC materials: dielectric constant>3500, sintered at<1150 ℃, meeting x7r specifications. (sintered at 1250℃, the dielectric constant can be greater than 4500.)
介電陶瓷:2000年用稀土,對BaZrTiO3陶瓷摻雜,得到了耐壓值也高達4KV/mm(AC),介電常數>2.5萬的Y5V高壓瓷料。
(3)Nano-scaled Ceramic powders: Developed a new method to synthesize perovskite nanomaterials directly from solution near or at room temperature under the normal pressure.
納米合成:2002年,發明了溶液直接合成法,實現了在常壓接近或在室溫下,鈦酸鹽系(包括鈦酸鋇、鈦酸鍶、鋯酸鋇等及其固熔體)納米顆粒的批量直接合成。2009年實現一些氧化物和復合氧化物室溫直接合成。
