Assignee:

Superior Micropowders LLC - Albuquerque NM

International Classification:

B29B 910

US Classification:

264 7, 264 9, 264 13, 75332, 75335

Abstract:

Provided is an aerosol method, and accompanying apparatus, for preparing powdered products of a variety of materials involving the use of an ultrasonic aerosol generator ( ) including a plurality of ultrasonic transducers ( ) underlying and ultrasonically energizing a reservoir of liquid feed( ) which forms droplets of the aerosol. Carrier gas ( ) is delivered to different portions of the reservoir by a plurality of gas delivery ports ( ) delivering gas from a gas delivery system. The aerosol is pyrolyzed to form particles, which are then cooled and collected. The invention also provides powders made by the method and devices made using the powders.

US Classification:

2523014R, 2523014 R, 2523046 R, 2523016 F

Abstract:

Phosphor powders and a method for making phosphor powders. The powders are oxygen-containing, such as metal oxides, silicates, borates or titanates and have a small particle size, narrow particle size distribution and are substantially spherical. The method of the invention advantageously permits the continuous production of such powders. The invention also relates to improved devices, such as display devices, incorporating the phosphor powders.
