摘要
Systematic studies on the preparation of sodium-silicate solutions of different compositions via the hydrothermal-microwave treatment of perlite with an NaOH solution were performed. The effect of various factors on the degree of SiO2 recovery and the reaction rate was studied. The application of microwave energy was established to intensify the process of hydrothermal treatment compared to conventional heating.
