摘要/Abstract

摘要： 利用sol-gel法并通过原位复合方法制备了具有铁电性能的PbTiO₃和具有铁磁性能的NiFe₂O₄和PbFe₁₂O₁₉多相复合体系陶瓷粉体.利用XRD、SEM对多相复合体系的物相结构和形貌等进行研究.结果表明,在700℃时可控制形成纯铁电(PbTiO₃)/铁磁(NiFe₂O₄)两相复合体系,在750℃以上则形成铁电(PbTiO₃)/铁磁(NiFe₂O₄和PbFe₁₂O₁₉)三相复合体系.热处理温度对多相复合体系晶相的形成和生长产生关键性作用.多相复合共存体系中形成的晶相多以固溶体存在,各固溶晶相的晶格常数随固溶量的不同而不同.

Abstract: Ferroelectric/ferromagnetic multiphase composite powders consisting of PbTiO3 as ferroelectricity and NiFe2O4 (PbFe12O19) as ferromagnetism were successfully formed in situ by the sol-gel method. The phase structure was measured by XRD and the morphology was observed by SEM. The results show that the biphase composite powder consisting of PbTiO3 and NiFe2O4 are formed at - 700℃ and the triphase composite powder consisting of PbTiO3, NiFe2O4 and PbFe12O19, above 750℃ in situ in alead-acetate/tetrabutyl-titanate/nickel-acetate/ferric-nitrate precursor system. The forming and growing processes are dependent on the calcination temperatrues of the powders. In addition, the phases coexisting in the composite system are mostly in forms of solid solutions, and the lattice constant of each phase varies with the different amount of phase solubility.
