Abstract

Microwave processing steps of 0.95[(K_0.5Na_0.5) _0.94Ag_0.06NbO₃]-0.05[LiSbO₃]/(KNAN- LS) lead free ferroelectric ceramics were optimized for better densification and electrical properties. Calcination temperature and time for single perovskite phase formation were optimized and found to be 850°C for 60 min., respectively. Crystal structural study revealed the presence of mixed structure in the microwave processed (MWP) KNAN-LS ceramics. The sintering of the KNAN-LS ceramics was carried out at 1080°C for 10 min, 20 min and 30 min, respectively, and the sample sintered for 20 min exhibited best properties.
