Method for producing alkali metal silicates |
| abstract |
Method for producing alkali metal silicates from crystalline siliceous material and aqueous alkali metal hydroxide solution at high temperature and normal pressure, characterized in that cristobalite and/or tempered quartz sand are used as the siliceous material, and this material is reacted with aqueous, 20 to 50 wt. % sodium or potassium hydroxide solution at temperatures of 100 to 150 °C and normal pressure, the molar ratio of SiO2 to Na2O or K2O in the reaction mixture being between 2:1 and 1:7. |
