	3	NEW LEAD-FREE PEROVSKITE RELAXOR CERAMICS DERIVED FROM BaTiO_(3)AND CONTAINING SCANDIUM显示文摘New lead-free compositions of AMO_(3)perovskite type were synthesized in the BaTi_(1-x)(Nb_(1/2)Sc_(1/2))_(x)O_(3)(0≤x≤1)system,with regards to the comparable electronic configurations of the various 6-coordinated cations.Special solid state reaction was used.The effect of the repla-cement of titanium by scandium and niobium in the B-site on structural and dielectric properties was investigated.For this,we have used X-ray diffraction and dielectric characterizations.Dielectric measurements performed on ceramics with 0≤x≤0.25 composition revealed that the small change in composition from BaTiO_(3)has a strong infuence on the dielectric properties:fast decreasing of the ferroelectric transition temperature for low values of x and evolution from classical ferroelectric for 0≤x≤0.075 to relaxor behavior for 0.075	ANNIE SIMON JEAN RAVEZ	2011	Journal of Advanced Dielectrics2011，1，2：	0
