Powders of composition La 1 & ndash; x Sr (Ca) x CoO 3 (x = 0.2) was obtained using the sol-gel method. To dry the gels, a microwave installation (radiation power 90 W, frequency 2450 MHz) and a drying oven (temperature 180 ° C) were used. Using the methods of thermogravimetry and differential scanning calorimetry, X-ray phase analysis, transmission electron microscopy, the properties, phase composition and morphology of particles of the obtained powders of complex composition were investigated.
