PURPOSE:To provide a manufacture of porous PZT ceramics being a molding with uniform density, namely, having uniform hole dispersion after baking in a manufacture of employing a slurry cast molding method of porous PZT ceramics for use in a high sensitive hydrophone for a water acoustic sensor. CONSTITUTION:A hole forming agent is added to PZT calcined powder and a binder is added to one which is dispersed by adding a dispersing agent thereto for making slurry. When slurry is molded by a method of slurry cast molding, slurry is flowed into a mold where molding is effected, while oscillating supersonic waves for imparting supersonic wave oscillation to slurry in the mold, by rendering suction and dehydration from the lower side of the mold by means of an aspirator. The molding thus obtained is then calcined in order to form a porous PZT ceramics body. |
