ABSTRACT:
A method and an apparatus for coating a hot glass substrate with a mist of fine droplets from a solution of a chemical precursor or mixture of precursors in a solvent, by nebulizing a solution with ultrasonic vibration to form a mist of fine droplets; conducting the mist to the hot glass substrate; and depositing the mist on the hot glass substrate to pirolize it and form the desired coating on the glass substrate. The nebulization is carried out by applying vibration of ultrasonic frequency to the solution obtaining the mist of fine droplets and conducting the fine droplets by a stream of a carrier gas, to be deposited on a surface of the hot glass substrate, particularly on a continuous glass ribbon during production in the float glass manufacturing process mainly at the beginning of the annealing chamber where the temperature of glass ribbon is 580.degree. C.-610.degree. C. The coated glass article resultant with this treatment is a spectrally selective reflective product which can be used for construction and automotive applications.
