Abstract
Glass powders and methods for producing glass powders. The powders preferably have a small particle size, narrow size distribution and a spherical morphology. The method includes forming the particles by a spray pyrolysis technique. The invention also includes novel devices and products formed from the glass powders.
Claims20
A method for the production of glass particles, comprising the steps of:
- a) generating an aerosol of droplets from a liquid wherein said liquid is an aqueous-based liquid comprising at least a first glass precursor;
- b) moving said droplets in a carrier gas;
- c) pyrolyzing said droplets in an elongated tubular furnace at a reaction temperature of from about 500° C. to about 800° C. and for a residence time sufficient to remove liquid therefrom and convert said precursor to form glass particles;
- and
- d) collecting said glass particles in a particle collector.
