Preparation of the Nano Crystalline Powder from Iraqi Sand using the Sol-gel Technology
Keywords:Nano Silica, ultrasonic, Scherer equation, Iraqi sand
AbstractIn this search nano silica powder was prepared by the bond fracturing of silica â€“ oxygen using wet chemical method at PH 1-2Â and by eliminate all undesired oxides by using ultrasound bath , and separating the compound by centrifuge ,and washing the product with distilled water ,and by separating and calcining the product at different temperatures it Weill is trail product with particle size ( 40-50) nm ,thenÂ XRD and AFM was to evaluate the product
