· The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity, it has an extremely low specific surface area in the range from 40 to 160 cm 2 /g. The material usually contains more than 99.7% SiO 2, with absorbed water being at a negligible level (0.1%).
Soda-lime silica glass combines three essential ingredients. Silica (sand) is the glass forming oxide, lime provides chemical stability and soda ash acts as the fluxing agent. Soda ash plays a vital role by reducing the furnace temperature necessary to melt the silica used, thus reducing the energy required to produce glass.
