비납계 Bi0.5Na0.5의 강유전 및 압전 특성에 미치는 Nb-doping 효과
Nb-doping Effects on Ferroelectric and Piezoelectric Properties of Pb-free Bi0.5Na0.5
E-mail:
Nb was doped to Pb-free (BNT) by a solid state mixing process to form (BNTNb) and its doping effects on ferroelectric and piezoelctric properties of BNT were investigated. The BNTNb solid solutions were formed up to x=0.01 with no apparent second phases while grain sizes decreased. As x increased, coercive field () and mechanical quality factor () decreased but piezoelectric constant () increased, which indicates Nb acts as a donor for BNT.
