Chemical Composition and Properties
Silicon, a metalloid, is the 14th most abundant element in the Earth’s crust. It is a naturally occurring substance, often found in the form of silicon dioxide (sand) or silicates (minerals). Silicon has a crystalline structure and is highly resistant to heat and corrosion. Its high purity and conductivity make it an essential material in the production of semiconductors, solar panels, and computer chips.
Silicone, on the other hand, is a synthetic polymer composed of silicon and oxygen atoms, combined with organic groups such as methyl or ethyl. It is created through a process of hydrolysis and condensation, resulting in a flexible and durable material. Silicone is known for its excellent thermal stability, resistance to chemicals, and ability to withstand extreme temperatures. Its versatility and wide range of applications have made it a staple in industries such as cookware, sealants, and medical devices.
