Abstract

The analytical control of titanium and impurities in piezoelectric ceramics are very important because they strongly influence
its electric and electromechanic properties. For example, If one piezoelectric ceramic is submitted to a strong electric field the impurities present can impede its polarization. The object of this paper is to establish an analytical procedure for the determination of titanium and impurities in piezoelectric ceramic. Several procedures for the dissolution of the sample were studied and it is found that the fusion with 3 :1 borax-carbonate mixture and later acid lixiviation was adequate. For the titanium determination two gravimetric methods were compared, one use cupferron and EDTA as precipitator agent and the other antipiryn and tanic acid. The
first method is not reported in the literature and the second is a reference method. The impurities of interest were determined by Atomic Absorption Spectroscopy using standard addition. The Ti and impurities were determined in two different reference
sample of BaTiO 3 and for a 95% on confidence no statistical significant differences were found between the reported results and the results of the methods.
