Perovskite niobates and tantalates have been placed on a short list of functional materials for future technologies. This article was investigated ferroelectric materials Ag(Ta,Nb)O3 thick film. In this study, we have fabricated the Ag(Ta,Nb)O3 thick film on the Al2O3 substrates by screen printing method. The Ag(Ta,Nb)O3 thick film were fabricated by the mixed oxide method. The sintering temperature and time were 1,150℃, 2 hr. The electrical properties of Ag(Ta,Nb)O3 thick film were investigated at 30∼100℃.
