Microstructural Properties of (Pb)(LaCe)$TiO_3$ ceramics as a function of $MnO_2$ addition

$MnO_2$첨가에 따른 (Pb)(La,Ce)$TiO_3$세라믹스의 미세구조특성

In this study, microstructural and dielectric properties of P $b_{0.83}$(L $a_{0.2}$C $e_{0.8}$)$_{0.08}$Ti $O_3$PCT ceramics as a function of Mn $O_2$ addition were investigated for 30MHz ceramic resonator application. Grain size was gradually increased according to the increase of Mn $O_2$ addition amount and showed the highest value of 1.502${\mu}{\textrm}{m}$ at the 0.9wt% Mn $O_2$. Moreover, density showed the highest value of 7.582 g/$\textrm{cm}^2$ at the 0.7wt% Mn $O_2$. All the composition ceramics, curie temperature was nearly constant around 33$0^{\circ}C$.EX>.>.>.
