Abstract

A synthesis process for PZT powder using NH$_3$ gas as a precipitator in a bubble column reactor was experimentally successful in develope a production process of Piezoelectric ceramic PZT powder. Also as a reaction by coprecipitation, the crystalized PZT ceramic powder at the condition of over pH 9 could be attained. The time needed for reaction on the condition of NH$_3$ gas flow rate=0.5 1/min, Ar gas flow rate=2.0 1/min, Feed flow rate=2.33 ml /sec was less than five minutes, so it could synthesize PZT powder for such a few moments. And the synthesized PZT powder was 0.17${mu}{ extrm}{m}$ in diameter on an average.
