    摘要: A method and a device for manufacturing a powder of amorphous ceramic or metallic particles in a high pressure autoclave. The substance in the liquid state is pressed out of a nozzle (7) upwards in vertical direction. An acoustic levitation field acts on the area in front of the nozzle orifice (12) and an inert cooling gas is made to flow turbulently in this area so that the droplets sprayed out of the nozzle are rapidly cooled and get solidified to grains. The powder can be directly machined by pressing and sintering into objects of the desired shape.

    摘要: The device disclosed comprises a high-pressure autoclave in which a moulded blank of the sample is heated by means of laser beams to the melting point and then rapidly cooled. The sample is maintained in a processing position (2) in an autoclave (1) without contact by means of an acoustic levitation device (12). Laser beams are directed through windows (19) in the autoclave onto the processing position and heat the sample. The molten sample then passes between two mutually impacting dies (20,21) by which it is crushed and thus rapidly cooled.
