【摘要】 本文研究了Al³⁺和Mn²⁺对YGdCaVIG的性能影响。掺Al³⁺和Mn²⁺都可使铁氧体电阻率增加,介电损耗下降,但掺Mn²⁺效果较好。掺入少量的Mn²⁺离子,铁氧体的密度和4πM_s变化不大,而电阻率较高,介电损耗较小。YGdCaVIG是一种少含稀土元素的石榴石铁氧体,Ca²⁺、V⁵⁺的加入使铁氧体的烧结温度下降了120℃,节省了能耗,改善了烧结条件。适当掺入Mn²⁺和选择最佳的烧结工艺,可以制备出性能优良的YGdCaVIG。更多还原

【Abstract】 The influence of Al³⁺ and Mn²⁺ on the properties of YGdCaVIG was studied.Adding Al³⁺ and Mn²⁺ in YGdCaVIG,the electrical resistivity of ferrite is increased,the dielectric loss is decreased. But adding Mn²⁺ is even more effective,adding Mn²⁺ in given range,there are little change in the density and the 4πMs,the electric resistivity is higher,the dielectric loss is smaller. YGdCaVIG is Yttriun iron garnet with little rare earth.Adding Ca²⁺ and V⁵⁺ in YIG,the sintering tempreture of garnet is decreased by 120℃,it may cut down the expense of energy and inaproves the sintering condition. The excellent YGdCaVIG is prepared by adding fit quantity of Mn²⁺ and selecting optimum the sintering process.更多还原
