Dielectric properties and IR-spectra are investigated of hydrated calcium lubricants, prepared from individual calcium soaps of higher fatty acids lauric, myristic, palmitic, x 14 stearic, behenic. It is shown that in hydrated calcium lubricants in the frequency range of 10 kHz-10 MHz and at a temperature of 20C the frequency dependency is manifested dispersion of dielectric constant and tangent of a dielectric loss angle. A supposition was advanced that the existence of the high-frequency and low-frequency maxima is due to the presence of two water forms in the system hydration water and that which is present in the crystal structure in a form of chain formations.
