The influence of ultrasonic dispersion power on the morphology, texture characteristics, and phase composition of CaSn(OH)6 samples synthesized by salt coprecipitation has been studied. The samples were characterized using X-ray diffraction analysis, scanning electron microscopy, and low-temperature nitrogen adsorption. The specific surface area of the samples is found to depend nonlinearly on the radiation power. Linear interpolation and Voigt fitting [1] were used to determine the linear sizes of crystallites according to the Scherrer principle [2]. The Keller–Miksis model [3] was used to calculate the critical bubble size at different impact powers and determine the “hot point” temperature at the instant of bubble collapse. It is shown that ultrasonic processing with a power density of 33 W/cm2 provides the highest collapse temperature at the smallest sizes of cavitation bubble (548 μm); in this case, the CaSn(OH)6 phase undergoes decomposition with the formation of calcium hydroxide Ca(OH)2 and amorphous tin oxide SnO2.
