Abstract

POSTUPAK ZA HIDROTERMALNO DOBIJANJE RASTVORA KALIJUMSILIKATA, pronalazak se odnosi na hidrotermalno dobijanje rastvora kalijumsilikata visokog molarnog odnosa SiO2:K2O, hidrotermalnom reakcijom kvarcnog peska sa vodenim rastvorom kalijumhidroksida na temperaturama u granicama od 150 do 300В°C, u reaktoru, i odgovarajućim pritiscima zasećene vodene pare koji odgovaraju ovim temperaturama, što ovako dobijeni rastvor kalijumsilikata, molarnog odnosa SiO2 : K2O manjim od 2,75 : 1, zatim reaguje sa temperiranim kvarcom, prethodno doveden do tačke topljenja na temperaturama iznad 1100В°C, uz ravnomerno održavanje temperature i pritiska u navedenim granicama.The invention relates to the hydrothermal production of a solution of potassium silicate with a high molar ratio of SiO2: K2O, by the hydrothermal reaction of quartz sand with an aqueous solution of potassium hydroxide, at pressures at 150 ° C corresponding to these temperatures, which thus obtained potassium silicate solution, molar ratio SiO2: K2O less than 2.75: 1, then reacts with tempered quartz, previously brought to the melting point at temperatures above 1100V ° C, while maintaining temperature and pressure in the above borders.
