【Abstract】 In this paper, the preparation of PZ-PT-PMN pyroelectric ceramics through the conventional elec- tronic ceramic preparing method is reported. Based on studies of crystal structure and atomic radius, several typical py- roelectric ceramics were designed and prepared. Parameters such as sintering temperature, sintering duration and the conditions of molding influencing pyroelectric and mechanical properties were also optimized. It is demonstrated that the properties of the pyroelectric ceramics are suitable for infrared detection.更多还原
