Abstract:
A chemical vapor deposition process for depositing a titanium oxide coating on a glass substrate at deposition rates of at least 130 .ANG./sec, comprising:(a) pre-mixing a uniform, precursor gas mixture containing titanium tetrachloride and an ester, said ester having an alkyl group with a .beta. hydrogen;(b) delivering said precursor gas mixture at a temperature below the thermal decomposition temperature of said ester to a location near a glass substrate to be coated, said substrate being at a temperature above the thermal decomposition temperature of said ester; andc) introducing said precursor gas mixture into a vapor space above said glass substrate wherein said ester thermally decomposes and thereby initiates a reaction with said titanium tetrachloride to produce a titanium oxide coating on said glass substrate.
