Silicon dioxide is a relatively inert material (hence its widespread occurrence as a mineral. Silica is often used as inert containers for chemical reactions. At high temperatures, it is converted to silicon by reduction with carbon. Fluorine reacts with silicon dioxide to form SiF4 and O2 whereas the other halogen gases (Cl2, Br2, I2) are unreactive.

WebJan 1, 2014 · Porous silicon materials are described as a mixture of air, silicon, and, in some cases, silicon dioxide. The optical properties of a porous silicon layer are determined by the thickness, porosity, refractive index, and the shape and size of pores and are obtained from both experimental- and model-based approaches. WebThese films have an amorphous structure and therefore their chemical composition can widely deviate from Si 2 N 2 O. By changing the nitrogen/oxygen ratio in these films, their refractive index can be continuously tuned between the value of ~1.45 for silicon dioxide and ~2.0 for silicon nitride.
