Copper(I) oxide - Wikipedia
Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu 2 O. It is one of the principal oxides of copper, the other being CuO or cupric oxide.This red-coloured solid is a component of some antifouling paints. The compound can appear either yellow or red, depending on the size of the particles. Copper(I) oxide is found as the reddish mineral cuprite
Silicon dioxide - Wikipedia
Silicon dioxide, also known as silica, is an oxide of silicon with the stone formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.
