Silica Characterization X-ray Fluorescence Spectroscopy (XRF) Chemical analysis was determined by using X-ray Fluorescence (XRF HORIBA, MESA 500-WX-ray fluorescence spectrometry with 15/50 keV X-ray tube. Quantitative analysis of silica content with no preparatory work such as calibration using standard samples and the pre-registration of a standard spectrum was performed. X-ray Powder Diffraction (XRD) Phase identification of silica extracted were determined by X-ray powder diffraction Phillips PW 1830/40 was used to determine the samples, using Cu-Kα1 radiation with λ = 1.5406 Å, generator tension 40 kV, generator current 30 mV in the range 5-70° 2θ and at a rate of 0.01°/min.
