Perlite Processing Method
摘要
A method for processing perlite with a 20% caustic soda solution at a temperature of 108°C was developed. The work was aimed at studying the processing of perlite at low temperatures, without autoclaving, without sintering, and with the extraction of a significant amount of useful components: aluminum oxide and silicon oxide with the production of sodium metasilicate nanohydrate, aluminosilicates of various metals, and crystalline SiO2.
