In the field of transformation of material there is a device for producing a plasma, a method for ionizing material using the device, uses of the inventive method and production processes using the device. The device includes a resonant chamber, an acoustic chamber provided with an acoustic device and a soliton chamber for receiving the treated material coming from the resonant chamber while simultaneously generating a recycling of outside air. The soliton chamber defines, with a pulsating suction member adjacent to the output of the soliton chamber, a space producing ionized material.
