Abstract
Methods for producing glass powders are provided. The methods include generating an aerosol stream comprising droplets that include a liquid and a glass precursor. Glass particles are formed in the aerosol stream having a small average particle size. The powders can also have a small particle size, narrow size distribution, a high density and a spherical morphology. The invention also includes devices and products formed from the glass powders.
Claims36
An aerosol method for making glass particles, the method comprising:
- generating an aerosol stream, as generated the aerosol stream comprising droplets comprising a liquid and at least one precursor for glass material;
- and
- in the aerosol stream, forming glass particles comprising the glass material, the glass particles having a weight average particle size of not greater than 5 microns and a particle density of at least 80% of the theoretical density of the glass material.
