Structural and Electrical Properties of $(Na_{0.5}K_{0.5})NbO_3$ ceramics addition with $BiTiO_3$

BiTiO3 첨가에 따른 (Na0.5K0.5)NbO3 세라믹스의 구조적 전기적 특성

We have studied structural and electrical properties of $(Na_{0.5}K_{0.5})NbO_3$ ceramics addition with $BiTiO_3$. The $(Na_{0.5}K_{0.5})NbO_3-BiTiO_3$ ceramics were fabricated by the conventional mixed oxide method, their dielectric and piezoelectric properties were investigated with the variations of additvie amount $BiTiO_3$. At the sintering temperature of $1130^{\circ}C$, the density, dielectric constant, grain size of 0.05mol% $BiTiO_3$ specimen showed the values of 4.69 g/$cm^3$, 898 and $24.8{\mu}m$.
