11.15 Glass Manufacturing US EPA
Commercially produced glass can be classified as soda-lime, lead, fused silica, borosilicate, or 96 percent silica. Soda-lime glass, since it constitutes 77 percent of total glass production, is discussed here. Soda-lime glass consists of sand, limestone, soda ash, and cullet (broken glass). TheIncompletely burned RHA is separated using a 45-mesh sieve, and there present no visible slag in the collected sample.

The flow chart for Silica Gel Production from wheat straw
Most ash samples showed silica as the main constituent (42-69%) and silica in crystalline form in all. Biosilica was obtained from ash samples using alkali extraction and acid precipitation.Rice hull ash (RHA) contains over 60% silica and can be an economically viable raw material for the production of silica based products. A previously published method for producing silica xerogel involved dissolving RHA silica with alkali solution to form sodium silicate solution and subsequently forming silica aquagel by adding hydrochloric acid to An improved method for production of silica from rice hull ash
