摘要: Abstract Low surface area SiO2 microspheres with narrow size distribution are prepared from wheat husk ash a facile precipitation process, in which four steps including the extraction of sodium silicate, dilution silicate extract distilled water and ethanol, silica HCl solution calcination process involved orderly. The particle specific resulted affected predominantly by volume ratio extract, ethanol dripping rate solution. synthesized internal mesopores have an amorphous structure diameters approximately 227 nm 8.23 m2/g under optimized synthesis conditions 1:1.5:0.5 for extract/water /ethanol 3 mL/min.
