Abstract A novel combinatorial synthesis method based on electric field-assisted combustion synthesis was developed to fabricate multiple ZrxTi1-xC solid solutions using Zr, Ti, and C elemental powders. The microstructure, phase composition, and near-infrared emission property of the prepared ZrxTi1-xC solid solutions with different Zr/Ti mole ratios were investigated. The prepared ZrxTi1-xC solid solutions all formed a single cubic structure. It was found that, the grain size of ZrxTi1-xC solid solution decreased as the ratio of Zr and Ti atoms approaches equal proportions. The emissivity of the ZrxTi1-xC solid solutions was 0.55-0.89 in the 0.25-2.5 μm wavelength range and exhibited an average emissivity over 0.80 for x = 0.7500, 0.5000, 0.1875, respectively.
