A method of producing homogeneous, fully reacted lead zirconate titanate powder, including additive elements, by reaction of the oxides of the constituent metals in a molten salt solvent was developed. Ceramics fired from different batches of powder made in this was showed good batch-to-batch reproducibility of electrical and piezoelectrical properties. Investigation of the influence on the properties of the resulting ceramic of variations in the way such powder is prepared for pressing and fired, revealed that nominally identical powders sometimes behaved differently. It is concluded that lead zirconate titanate powder still cannot be characterized so as to predict, except in a general way, the properties of the ceramic fired from it. Author
