Silicon dioxide is a very thermodynamically stable compound. In most labs I have been in, $ce{SiO2}$ is equated to sand whenever we aren't explicitly talking about silica gel (or sometimes celite, but that tends to get referred to as celite). Considering how hard it is to make anything out of sand that isn't essentially still a $ce{SiO2}$-derived compound should point to …

The Origins of Silicone: Understanding the Raw Materials. The journey of silicone production begins with the extraction of its primary raw material, silicon dioxide (SiO2), commonly known as silica or quartz. Found abundantly in sand, quartz is the second most abundant mineral on Earth. To convert silica into silicon, the material undergoes a ...
Quartz sand as the natural source of silica was sampled from Tanjung Tiram District, Asahan Regency, North Sumatra in which the extracted silica were utilized and chemically reduced into silicon. Extraction of silica from quartz sand was conducted by adding 10 N NaOH solution and 6 N HCl in three different phases.
