Abstract
The invention provides a method for preparing a metal powder, in which an ultrasonic vibration is induced on a perforated membrane that is in contact with a liquid metal. The metal is a low-melting-point metal or an alloy based on such a metal and which has a low melting point. The resulting metal powder is deposited directly onto/into a deposition target.

Method for preparing a metal powder, in which an ultrasonic vibration is induced on a perforated membrane that is in contact with a liquid metal.
Method for preparing a metal powder, comprising the use of an ultrasonic spraying device comprising a perforated membrane, in which the perforated membrane is in contact with a liquid metal and the ultrasonic vibration of the perforated membrane is generated by means of a sonotrode immersed in the liquid metal or a piezo-electric producing the metal powder which is collected directly onto/into a deposition target.
Method for preparing a metal powder, comprising the following steps:
- (a) a liquid metal is introduced in a container associated with an ultrasonic spraying device, wherein the container comprises a perforated membrane, wherein the liquid metal is in contact with the perforated membrane;
- (b) an ultrasonic vibration of the perforated membrane is induced by means of a sonotrode immersed in the liquid metal or by means of a piezo-electric, producing the metal powder;
- and
- (c) the metal powder is collected on/in a deposition target.
Ultrasonic spraying device adapted for producing a metal powder, comprising:
- a reservoir adapted to receive a liquid metal and comprising a perforated membrane;
- and a sonotrode or a piezo-electric integrated in the reservoir in which,
- when an ultrasonic vibration of the perforated membrane is induced, the metal powder is produced and collected directly onto/into a deposition target.
Ultrasonic spraying device adapted for producing a metal powder, comprising:
- a reservoir adapted to receive a liquid metal and comprising a perforated membrane;
- and a sonotrode adapted to be immersed in the liquid metal in which when,
- an ultrasonic vibration of the perforated membrane is induced, the metal powder is produced and collected directly onto/into a deposition target,
- optionally the sonotrode is spaced apart from the perforated membrane,
- optionally the sonotrode is in contact with the perforated membrane.
