Methyltrichlorosilane
Methyltrichlorosilane results from the direct process of chloromethane with elemental silicon in the presence of a copper catalyst, usually at a temperature of at least 250 °C.Poly(methylsilyne) is soluble in organic solvents, and can be applied to surfaces before being pyrolyzed to give the ceramic material, silicon carbide.Because of the stability of the cross-linked polymers resulting from condensation, the resin is stable to 550 °C in a vacuum, making it an ideal material for electrical insulation at high temperatures.[1] These resins can be used to coat computer chips or other electronic parts since they both repel water and provide thermal isolation.Chloride is used to reduce the tendency of silicon to react in the gas phase and thus to increase the growth rate of the process.
