Abstract：The MnCO3 carbonate and ferro bismuth BiFexCO3 subcarbonate were selected as raw materials, Bi(Fe0.9Mn0.1)O3 powder particles were prepared by wet ball grinding and calcining, and the influence of calcining temperature on its performance was studied. The results show that the precursor contains MnCO3 and BiFexCO3, and the calcining temperature of the precursor is set between 455-820 ℃. The microstructure and agglomeration morphology of samples are significantly affected by the calcination temperature. When the temperature reaches 700 ℃, spherical and polyhedral particles with particle sizes between 120-280 nm are formed. All samples have similar background contrast, and there are no different regions with significant difference in light and shade, indicating the uniform distribution of the manganese and bismuth form. The products formed by calcination at 600-800 ℃ have high near-infrared reflectivity for all bands, especially when the temperature rises to 700 ℃, they have excellent reflection performance.
