Abstract

Systematic investigation of the possibility of using microwave (MW) energy for obtaining of silicates as pigments for the thermoregulating coating for the first time has been carried. Were obtained sodium and potassium silicate solutions different composition by hydrothermal microwave (HTN MW)treatment diatomite. Kinetic regularities were studied and were revealed the conditions obtaining of sodium and potassium silicates solutions using MW heating. The effect of various factors on the degree of SiO2 recovery and the reaction rate was studied.
