摘要

采用传统的固相烧结工艺制备得到 Ca1-xLaxMnO3(CLMO), Ca1-xBixMnO3(CBMO)(x＝0.0～0.2)陶瓷样品, 通过 XRD和 FT-IR对样品进行表征, 研究了晶体结构, 温度和不同波段下的红外发射率之间的关系。研究结果表明：CLMO和 CBMO陶瓷样品具有单一物相。晶格畸变产生了新的红外吸收带。CLMO和 CBMO陶瓷在 8～14 μm波段的红外发射率随着温度的升高而升高, 在 400℃左右红外发射率发生突变。在 3～5 μm波段的红外发射率随着温度的升高而缓慢升高。CLMO和 CBMO陶瓷样品在 8～14 μm波段具有作为热控制材料的潜在应用前景。

Abstract

Ca1-xLaxMnO3(CLMO) and Ca1-xBixMnO3 (CBMO)(x＝0.0-0.2) ceramics were prepared by standard solid-state reaction method. The samples were characterized with XRD and FT-IR. The relationship of the structure, temperature and normal emissivity in different wavebands was investigated. The results show that the samples have single phase. New infrared absorption occurs due to crystal distortion. In the 8-14 μm waveband, the normal emissivity of CLMO and CBMO ceramics increases with increasing temperature, and the drastic change occurs at the range of 400℃. In the 3-5 μm waveband, the normal emissivity of CLMO and CBMO ceramics gradually increases with increasing temperature. Therefore, CLMO and CBMO ceramics may have the potential application as thermal control materials.
