By controled burning of bagasse ash at 650º C for 2 h, obtained a reactive material relatively free from organic
mater. Metalic impurities with trace elements in bagasse ash got destroyed in the formation of nanosilica. XRD
spectrum shows that the silica is in amorphous nature. FTIR peak confirmed that the nanosilica belongs to the
siloxane and silanol groups. SEM micrograph of nanosilica shows that the particles are almost spherical,
homogeneous and agglomerated form. SEM-EDS report the silca particle is 90 nm in size and of 99% purity.
The study reveals that the industrial waste material sugarcane bagasse ash acts as an alternative source for the
production of silica.
