COATING GLASS

摘要

A coating consisting of or containing silicon is produced on glass by moving the glass, at a temperature of at least 400.degree.C, past a coating station to which silanecontaining gas is supplied. The gas is released close to the glass surface into a hot zone opening towards the glass surface and at a substantially constant pressure across that surface. Non-oxidizing conditions are maintained in the hot zone, and the coating is produced by pyrolysis of the gas on the glass surface.
