Function in Products
Silica: a naturally occurring common mineral vital to human cellular health. Silica nourishes the skin and helps reduce the appearance of fine lines and wrinkles. Silica is required for the proper functioning of the enzyme prolyhydroxylase. This enzyme is vital in the formation of collagen in skin, connective tissue, bone, and cartilage. Silica aids in healthy skin, hair, and nails and is particularly beneficial to acne prone skin.
Silicon exists as its oxide in nature. Silica is an example of that, with the molecular formula of SiO2 (silicon dioxide). Silica is an abundant mineral in earth crust, and it is in sand, quartz, and many other minerals. Some minerals have pure silica, but in some silica is mixed with other elements. In Silica, the sulfur and oxygen atoms joined by covalent bonds form a huge crystal structure. Each sulfur atom is surrounded by four oxygen atoms (tetrahedrally). Silica doesn’t conduct electricity, because there aren’t any delocalized electrons. Further, it is highly thermo stabilized. Silica has a very high melting point, because a large number of sulfur-oxygen bonds have to be broken in order to melt it. When it is given a very high temperature and cooled at a certain rate, the melted silica will solidify to form glass. Silica doesn’t react with any acid except hydrogen fluoride. Moreover, it is not soluble in water or any organic solvent.
Not only silica is abundant in the earth crust, but it is also present inside our bodies in considerable amounts. Silica is needed for healthy maintenance of bones, cartilages, nails, tendons, teeth, skin, blood vessels, etc. It is naturally present in water, carrot, bread, cornflakes, white rice, banana, raisin, etc. Also, silica is widely used in ceramic, glass and cement industries.
What is the difference between silicon and silica?
- Silicon is a single atom; silica is a molecule, which is an oxide of silicon.
- Silica has a higher melting point than silicon.
- Silicon is a semiconductor, but silica doesn’t conduct electricity.
- Very rarely silicon exists as the pure compound, but silica is very abundant on earth.
- Crystal silicon is very brittle, but crystal silica is hard.
