摘要
在超声-微波场作用下,对铟铁酸锌(ZnFe_(2-x)In_(x)O_(4))中铟进行强化碱浸。结果表明,铟不能在ZnFe_(2-x)In_(x)O_(4)八面体晶格中大量固溶,最大固溶量约4.0%(质量分数,对应x=0.088);外场对铟浸出的促进作用大小顺序为:叠加超声-微波复合场>微波单场>顺序复合场>超声单场;在叠加超声-微波复合场下铟浸出率达56.6%,而超声单场下铟浸出率为30.2%;外场作用下碱浸,将In^(3+)从晶格中释放出来,不会使铁酸锌的八面体晶格坍塌;叠加超声-微波复合场下浸出的In^(3+)较多,样品的晶格常数下降较大,衍射峰强度降低与右移现象明显。
Alkali leaching of indium from zinc indium ferrite(ZnFe_(2-x )Inx O_(4))was strengthened by applying a combination of ultrasound and microwave.The results show that there are not a great amount of solid solution of indium in the octahedral lattice of ZnFe_(2-x)In_(x)O_(4),and the maximum solid solution approaches 4.0%in a mass fraction(x=0.088).The leaching rate of indium can be enhanced by the external fields in the following descending order:a combined application of ultrasound and microwave,single application of microwave,application of ultrasound followed by microwave or microwave followed by ultrasound,and single application of ultrasound.It is shown that the leaching rate of indium can be up to 56.6%with a combined application of ultrasound and microwave,but only reach 30.2%by singly applying ultrasound.During the alkaline leaching under the external fields,In3+can be released from the lattice,while the octahedral lattice of zinc ferrite will not collapse.With a combined application of ultrasound and microwave,more In3+can be released,leading to lattice constant becoming much smaller.The XRD spectrum shows obvious reduced intensity and rightward movement of diffraction peaks.
