ABSTRACT:
A method is provided for producing bismuth and bismuth alloy shot particles by a procedure whereby molten bismuth at a temperature less than about 100.degree. C. above the melting point of the bismuth is used to form drops of molten bismuth which fall through a vessel containing a material more viscous than water with the method having a Reynolds Number less than about 100. Preferred materials are polyethylene glycols having a molecular weight of about 4500 and 8000.
