Method of processing materials using an inductively coupled plasma
Patent
·
OSTI ID:6457067
This patent describes a method of making fine powder in a gas-free environment using an electrically conductive ceramic or metal starting material which is initially in solid form. It comprises: providing inductively coupled plasma apparatus; placing the starting material within the radiation shield; evacuating the tubular enclosure; heating the starting material by use of the induction coil to vaporize the starting material and to form a plasma from the resulting vapor; and utilizing a powder collection surface adjacent to the outlet of the plasma apparatus to collect material emanating from the outlet.
