摘要
用常规固相合成法成功地制备出Ni^3+和Cr^3+掺杂的尖晶石型材料,并通过XRD,IR光谱和红外辐射仪测试了材料的微观结构,分析了材料的结构特征与红外辐射性能的关系,发现Ni^3+和Cr^3+的掺杂导致Ni^3+和Cr^3+分别以一定的配位形式进入体系中,并形成了(□,Fe)(□,Mn)2O4型尖晶石结构,数据分析可知,体系在全波段的积分辐射率为0.93,在〈8μm波段样品具有较低的平均辐射率值为0.79,而在8~25μm波段的平均辐射率最高值可达0.97。
Ni^3+ and Cr^3+ doped spinel infrared radiation material was prepared by solid phase sintering.Microstructure and performance of that were studied by XRD,IR and IRE-2 infrared radiant instrument.Ni^3+ and Cr^3+ occupied the position in the structure by right coordination and formed(□,Fe)(□,Mn)2O4 spinel structure,which changes lead to improve of infrared radiation property as the content of Ni2O3 increases.The infrared radiation properties are obtained in the samples,exhibiting the infrared emissivities of 0.93 in the whole bands,and infrared emissivities of 0.97 in the bands within 8~25μm too,but with low infrared emissivities in the bands less than 8μm.
