Jul 01, 2000 Abstract. Rice hull ash RHA, a waste product of the rice industry is rich in silica. A simple method based on alkaline extraction followed by acid precipitation was developed to produce pure silica xerogels from RHA, with minimal mineral contaminants. The silica gels produced were heated to 80 o C for 12 h to obtain xerogels.
