Silica
It is mainly found in the form of quartz (granite, pegmatites, quartzite, sand) and to a lesser extent, cristobalite and tridymite (volcanic rocks). Silica powder is white in appearance. The density of silicon dioxide is 2.334 g · cm-31. Its bulk density depends on the method of densification, but it is generally between 400 and 650 kg / m³.
