POROUS PIEZOELECTRIC MATERIAL MOLDED BODY, METHOD OF MANUFACTURING SAME, AND PROBE USING SAID MOLDED BODY
[Problem] To provide a porous piezoelectric material molded body which has high utility as a constituent member of a piezoelectric vibrator suitable for, in particular, a probe for an ultrasound medical diagnostic device. [Solution] A porous piezoelectric material molded body in which 1000 or more per cubic millimeter of spherical pores having an average pore diameter in a range of 2 to 70 [mu]m are dispersed and formed. The porous piezoelectric material molded body is characterized in that the spherical pores do not include substantially pores with a pore diameter exceeding 50 [mu]m, and thatthe pores occupying 80% or more of the entire volume of the pores constituting the spherical pores have a pore diameter of within +/-20% with respect to the average pore diameter.
本发明提供一种多孔压电材料成型体，其非常适合用作压电换能器的构成材料，该压电换能器适合用于医学超声诊断设备的探针。多孔压电材料成型体的特征在于，在每1mm3体积的压电材料中分散形成有1000个以上的平均孔径在2‑70μm的范围的球形孔组，其中，几乎不存在孔径超过50μm的球形孔，并且构成球形孔组的总孔的80体积％以上的孔具有所述平均孔径的±20％以内的孔径。
