WATER FREEZING IN THE DISPERSION OF HYDROPHOBIC SILICA ACCORDING TO PROTON MAGNETIC RELAXATION SPECTROSCOPY
he relations between the spectral parameters of the spin-spin relaxation time of hydrophobic silica dispersion («dry water») with its micro-structure were established. The processes of water drops freezing in the dispersion of «dry water» were investigated with the help of nuclear magnetic relaxation spectroscopy. It was determined that the water crystallization speed in the dispersion of «dry water» depends on the speed of the formation of viable ice germ in the micro-drops of the dispersed phase. The effect of freezingthaw cycles on the «dry water» micro-structure was ascertained.
