ABSTRACT:
A method for generating an aerosol powder from a melt includes an atomization die having an orifice through which the melt passes to create the powder. In a preferred embodiment, the orifice has a dimension less than 5 millimeters, and may include a heater to prevent freeze-off. The die may be included in a high-temperature probe suitable for immersion on the melt, so that accumulated accretions of powder on the walls of the probe may be melted off by heating the probe.
