摘要(Abstract)：

利用碘化钾分光光度法测定Bi的标准曲线,并用以分析溶胶-凝胶法制备得到Bi_(0.7)Y_(2.0)Ca_(0.3)Zr_(0.3)Fe_(4.7)O_(12)石榴石纳米颗粒的Bi⁽³⁺⁾含量.实验表明,当钇铁石榴石样品的煅烧温度越高时,Bi(3+)含量.实验表明,当钇铁石榴石样品的煅烧温度越高时,Bi⁽³⁺⁾的损失量越大.当煅烧温度为700℃以下时,Bi(3+)的损失量越大.当煅烧温度为700℃以下时,Bi⁽³⁺⁾损失量在3%以内,当煅烧温度分别为800、900℃和1 000℃时,Bi(3+)损失量在3%以内,当煅烧温度分别为800、900℃和1 000℃时,Bi⁽³⁺⁾的损失量为4.53%,9.74%和17.73%.Bi(3+)的损失量为4.53%,9.74%和17.73%.Bi⁽³⁺⁾的损失量与煅烧温度满足高斯变化规律,该结果可为石榴石铁氧体中Bi(3+)的损失量与煅烧温度满足高斯变化规律,该结果可为石榴石铁氧体中Bi⁽³⁺⁾含量提供依据.
