A chemical vapor deposition process for the deposition of a silica layer on a glass substrate is provided. The process includes providing a glass substrate. The process also includes forming a gaseous precursor mixture comprising a silane compound, oxygen, water vapor, and a radical scavenger and directing the precursor mixture toward and along the glass substrate. The mixture reacts over the glass substrate to form a silica coating thereon.
