A group of minerals containing various amounts of the elements Silicon and Oxygen. The Silicates are the largest group of minerals. The construction component of all Silicates is the tetrahedron, which is one Silicon atom equidimensionally placed around four Oxygen atoms.
Silicon readily bonds with oxygen and is rarely found in nature in its pure form. You've likely seen silicon as silicon dioxide or silica, better known as quartz, which is the most common component of sand. Silica also comes in other mineral forms, such as flint, jasper and opal.When silicon and oxygen mix with reactive metals, the result is a class of minerals called silicates, which includes granite, feldspar and mica.Silicon has many industrial uses: As silica, silicon is a key ingredient in bricks, concrete and glass.hen silicon and oxygen mix with reactive metals, the result is a class of minerals called silicates, which includes granite, feldspar and mica.
