| Abstract: | Adequately mix the light silicon ash and lime with the quality ratio 1 ∶1,and get the silicate materials through sintering at 1 100 ℃ for 0.5 h.According to the solid and liquid weight ratio 1 ∶7.5 put the silicate materials in hydrochloric acid solution to dissolve,after diluting,rinsing,filtrating and drying,etc,the silica white samples with the whiteness is 96,the granularity is 11.15 μm,and the purity of SiO2 is 99.9% are obtained. |
