Abstract
0.75BF-0.25BT ceramics were prepared by sintering at $980-1040^{\circ}C$ in air or under atmosphere powder. A sample with 1 mole %-excess $Bi_2O_3$ was also prepared to compensate for $Bi_2O_3$-evaporation. Physical and piezoelectric properties of these three samples were compared. When the sintering temperature increased from $980^{\circ}C$ to $1040^{\circ}C$, the density of the sample sintered in air decreased continuously due to Bi-evaporation. Due to the suppression of Bi-evaporation, the sample sintered under atmosphere powder had a higher density at sintering temperatures above $1000^{\circ}C$ than did the sample sintered in air. The addition of 1 mole %-excess $Bi_2O_3$ successfully compensated for Bi-evaporation and kept the density at the higher value until $1020^{\circ}C$. Grain size increased continuously when the sintering temperature increased from 980 to $1040^{\circ}C$, irrespective of the sintering atmosphere. When the sintering temperature increased, the piezoelectric constant ($d_{33}$) and the electromechanical coupling factor ($k_p$) increased for all samples. The sample with 1 mole % excess-$Bi_2O_3$ showed the highest density and the best piezoelectric properties at sintering temperature of $1020^{\circ}C$.
