Patent Summary

A device for crucible-free melting of materials and atomizing molten materials to produce powders through controlled atomization. The device features an induction coil with narrowed turns and a precision atomizing nozzle that can be precisely positioned within the coil. The nozzle is designed to direct the molten material stream into the sputtering gas through a controlled opening, allowing atomization while minimizing heat transfer to the nozzle. The device achieves high-temperature melting and atomization through its optimized coil design and precise nozzle positioning, enabling the production of powders with controlled grain size and distribution.
