摘要
采用固相法制备了Zn2+固溶堇青石体系红外辐射材料,并对材料的结构及红外辐射性能进行了研究。在2(1-x)MgO·2xZnO·2Al2O3·5SiO2(x=0～0.6)体系中,x≤0.3时,可得到六方结构的堇青石固溶体;x>0.3时,体系中镁铝尖晶石成为主要物相。x=0.2时,样品的红外辐射性能最佳,其法向全波段的辐射率达到0.89,8～14μm波段的辐射率达到0.91以上。
Infrared radiant materials of Zn2+substituted cordierite solid solutions were prepared by solid reaction method. Microstructure and infrared radiant characteristics of materials were investigated. In the Mg2(1-x)Zn2xAl4Si5O18(x=0～0.6) system, cordierite solid solution with a hexagonal crystal structure can be prepared for x up to 0.3. When x>0.3, Zn2+substituted MgAl2O4 is major phase. Optimum infrared radiant characteristics can be obtained in the sample of x=0.2, which exhibits infrared emissivities of 0.89 and 0.91～0.94 in the whole band and 8～14μm band, respectively.
