Abstract

Described are methods and apparati for the rapid solidification of molten materials into finely divided particulate form. Molten material is atomized by a centrifugal atomizer which includes a rotating member with vanes which accelerate and atomize the molten material. The mist of atomized molten material thus produced is introduced into a mist of atomized liquid coolant or a mist of finely divided volatile solid coolant or a mixture thereof. The heat of solidification of the mist of molten material is rapidly transferred to the mist of coolant whereby the molten material solidifies into fine particles.
