Abstract:
Rice husk ash was used to produce sodium silicate with SiO2/Na2O=3. The investigation of NaOH concentration and temperature on the silica conversion showed that NaOH has positive influence. SiO2/Na2O 3 was produced with 0.8 mol/l of NaOH and 403/453 K. These solutions were used to produce silica sol with diameter of 5nm.
