Abstract
An atomizer disk for use in the process of making metal powder by pouring molten metal onto the spinning disk is made from a plurality of contiguous, concentric, radially aligned elements having thermal conductivity properties which are selected to achieve appropriate temperature zones on the surface of the disk during operation. The central disk-like element is preferably a ceramic with low thermal conductivity. The outermost element is a high strength reinforcing ring which preferably also has high thermal conductivity. The annular elements between the outer ring and central disk should also have high thermal conductivity. By properly selecting the disk materials the heat extraction from the molten metal can be better controlled and larger disks may be constructed.
