Jul 24, 2019· Silica, also known as silicon dioxide, is mined from quartz and can also be synthesized in a lab, but is also found in plants such as horsetail, oats, barley, etc. At a guess, the difference may be that when it is processed by a plant it becomes biofriendly to our bodies, whereas the mined silica remains non biofriendly.
At first glance, quartz glass appears very simple, both chemically and structurally, since it is made from a single oxide component (silicon dioxide – SiO 2).. Chemical structure: Silica, as it is also known, is found throughout the earth''s crust. However, only a small fraction has sufficient purity (> %) to be suitable as raw material for quartz glass.
