How are silicones made
WebAs an electric current passes through the electrodes on the lid of the furnace, it forms an arc that generates heat up to 4,000°F or 2,350°C. The high temperatures trigger a reaction where the oxygen is removed, leaving behind silicon and carbon monoxide. The entire reduction process takes approximately six to eight hours. WebThe main sources of silicone are natural origin silica stone (SiO 2), water, and natural gas-derived methanol. From these materials, through complex chemical reactions, silicone is synthesized. Taking the most widely …
