This paper details a study of the influence of Lead Zirconate Titanate (PZT) powder preparation and milling process on the d33 coefficient of thick-film PZT layers. In particular, the influence of the powder milling process and its effect on particle size, shape and distribution has been investigated. Ball milled, jet milled and attritor milled powders were obtained from Morgan Electro Ceramics Ltd. These powders were mixed with various ratios of lead borosilicate glass in the range 5 to 20% by weight and an appropriate quantity of ESL 500 solvent to formulate a screen printable paste. The results show the highest values of d33 were obtained from the ball milled powder with 10% glass content, but the most consistent results were obtained from the attritor milled samples.
