Abstract:
A combinatorial chemistry method was employed to screen the Ba2+ and Fe3+ incorporated into cordierite structure (Ba0.05Fe0.1Mg)2Al4Si5O18 for exploring of high infrared radiance materials. A series of square-type sample array that consists of 7×7 compositions was syn-thesized by ink-jetting nitrate solutions into micro-reactor wells in a ceramic plate and then heat-treated at high temperatures. X-ray diffraction and infrared thermograph were used to analyze the effects of Ba2+/Fe3+ incorporating on the lattice distortion of cordierite and resultant changes in infrared radiance properties. Based on the results of X-ray phase analy-sis and radiance measurement of the scale-up prepared samples, the optimal Ba2+ and Fe3+ co-adding amount was determined to be 5%Ba2+ plus 10%Fe3+. Moreover, the infrared emissivity of the optimal composition at 100 oC was found to be higher than 0.8 in a wide wavelength range of 5-24 μm. The research work demonstrates a promising application of Ba2+/Fe3+ cordierite solid solution as a kind of infrared heating materials for energy saving.

摘要:
采用组合材料方法制备并筛选了具有高红外辐射性能的Ba/Fe共掺堇青石固溶体(Ba0.05Fe0.1Mg)2Al4Si5O18. 通过组合溶液喷射法,制备了7×7阵列的样品库,并在不同温度下进行热处理.通过X射线衍射、红外热成像等测试方法分析了Ba2+、Fe3+固溶对堇青石晶格畸变和红外辐射性能的影响. 经过放大制备实验的验证,确定了材料的最佳组分为5%Ba2+和10%Fe3+共固溶的堇青石. 最佳组分样品在100 oC时的红外辐射率在5-24 μm波段均高于0.8.
