What's the difference between Silicon and Silicone ? Silicon is a natural chemical element (Si) found in great abundance on Earth, primarily as a major component of common sand. Silicone on the other hand is a man-made substance derived from silicon and other chemicals. Silicones are used in sealants, adhesives, lubricants, medical applications, cookware, and insulation.
