FIELD: physics.
SUBSTANCE: powdered piezoceramic material is mixed with powdered blowing agent. The powdered blowing agent used is pre-sintered starting piezoceramic material with particle size of 10-20 mcm in amount of 40-60 wt %. A polyvinyl plasticiser is added. The workpiece is pressed and burnt.
EFFECT: reduction of pore size to 1-5 mcm, high relative porosity of the composite piezoelectric material, mechanical quality factor and wider operating band of the transducer made from the disclosed piezoelectric material.
