Abstract
Perovskite niobates and tantalates have been placed on a short list of functional materials for future technologies. This article was investigated ferroelectric materials $Ag(Ta,Nb)O_3$ thick film. In this study, we have fabricated the $Ag(Ta,Nb)O_3$ thick film on the $Al_2O_3$ substrates by screen printing method. The $Ag(Ta,Nb)O_3$ thick film were fabricated by the mixed oxide method. The sintering temperature and time were 1,150$^{\circ}C$, 2 hr. The electrical properties of $Ag(Ta,Nb)O_3$ thick film were investigated at 30~100$^{\circ}C$.
