Article Preview

High emissive Ca2+/Fe3+-doped LaAlO3 based ceramic materials were prepared by flame spraying and controlled crystallization method. The phase composition, microstructure, infrared optical properties of Ca2+/Fe3+-doped LaAlO3 based ceramic powders were investigated. The physical mechanism for the significantly enhanced infrared emissivity of LaAlO3 by doping with Ca2+ and Fe3+ was analysized. This high emissive Ca2+/Fe3+-doped LaAlO3 based ceramic materials shows promising applications in high temperature thermal process field to enhance the radiative heat transfer and improve its thermal efficiency.
