Abstract: A coated glass article provides a visible light reflecting, solar control glazing with a low emittance, a low solar heat gain coefficient, and a low shading coefficient that can significantly improve energy costs in buildings and homes while providing a desirable neutral color for, at least, film side reflection. The low emittance characteristic of the 5 glazing would minimize any indirect heat gain from absorption.

Abstract: A chemical vapor deposition process for forming a silicon oxide coating includes providing a moving glass substrate. A gaseous mixture is formed and includes a silane compound, a first oxygen-containing molecule, a radical scavenger, and at least one of a phosphorus-containing compound and a boron-containing compound. The gaseous mixture is directed toward and along the glass substrate. The gaseous mixture is reacted over the glass substrate to form a silicon oxide coating on the glass substrate at a deposition rate of 150 nm*m/min or more.
