Outline of Final Research Achievements

Ceramics with hemispherical shell structure and several millimeter in diameter was fabricated using following two methods; (1) a method using a template made of 2 D close-packed polymer spheres (2) a slip casting method. By method (1), unfortunately, it was difficult to maintain hemispherical shell structure after annealing the film deposited on the template. On the other hand, fabrication of target structure was successfully realized and PZT ceramics having hemispherical shell structure were fabricated. It was proved that the sample shows distinct pyroelectric properties. In addition, fabrication of array structure using the hemispherical shell structure was also achieved.
