Abstract
In this paper the dependencies of particle size distribution, phase composition, diffuse reflection spectra, absorption spectra, and emissivity of powders from the mixtures La2O3 + SrCO3 + MnCO3 on a synthesis temperature in the range of 800–1200 °C are investigated. Samples were characterized using X-ray diffraction (XRD), high resolution scanning electron microscopy (SEM), and a spectrophotometer. It is found that the basic compound La(1−x)SrxMnO3 is formed even at such low temperature as 800 °C with a heating time of 2 h. An explanation of the processes occurring in the synthesized powders was suggested. The conclusion about the possibility of obtaining the powder-pigments for the absorbing smart temperature stabilizing coatings by high-temperature synthesis without the use of mechanical effects was made.
