Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a piezoelectric material powder (bismuth titanate powder) for an ultrasonic thickness measurement sensor formed of oxide based ceramic of bismuth titanate which is thin and flexible, and can be used at a high temperature of about 400°C, achieving piezoelectric properties required for an ultrasonic thickness sensor, in particular.SOLUTION: The method includes: a mixing step of mixing titanium oxide powder and bismuth oxide powder; a heat treatment step of heating the mixture powder obtained in the mixing step at a temperature in the range of 750°C to 900°C for synthesis of bismuth titanate; and a pulverization step of pulverizing the bismuth titanate obtained in the heat treatment step into powder.
