“…The slurry is composed of precursor and PZT powder. Four chemicals are involved in precursor solution preparation [5][6]: lead acetate trihydrate (Pb(CH3COO) 2 • 3H 2 O), zirconium n-propoxide (Zr(OCH 2 CH 2 CH 3 ) 4 ), titanium nbutoxide (Ti(OC 4 H 9 ) 4 ), and 2-methoxyethanol (CH 3 OCH2CH2OH). Firstly, lead acetate trihydrate (13.28 g), zirconium n-propoxide (8.18 g), and titanium n-butoxide (7.09 g) were respectively dissolved in 2-Methooxyethoanol (86.72, 41.82, 42.91 g) and refluxed at 130 °C for 2 h. These three solutions were then stored in individual glass bottles for further processing.…”
