摘要
采用X射线晶胞常数法测定了FeAl2O4在MgAl2O4中的固溶量,相对误差2.90%。MgA12O4中的Mg2+被Fe2+取代,形成(Mg,Fe)Al2O4固溶体,其晶胞常数随FeAl2O4含量的增加而增大,而且固溶量是晶胞常数的线性函数,因此可以根据晶胞常数准确测定FeA2O4在MgAl2O4中的固溶量。方法简单易行,合理可靠。
The solid solution content of FeAl2O4 in MgAl2O4 was determined by X-ray diffractometry using cell constant method. The relative error is 2.90%. The solid solution of (Mg,Fe) Al2O4 was formed when Mg^2+ in MgAl2O4 was replaced by Fe^2+ . The cell constant of (Mg,Fe)Al2O4 increases with the increase of FeAl2O4 and the solid solution content is a linear function of cell constant. So that the solid solution content of FeAl2O4 in MgAl2O4 can be determined accurately based on cell constant. The method is simple, reliable and accurate.
