ABSTRACT:
A method of treating molten metals comprising heating and extruding into the lower portion of a vessel containing the molten metals, an extrudable composition. The extrudable composition commprises calcium metal and sodium metal with said sodium being present up to about five percent by weight of the composition. The sodium metal has a volume distribution defining a more or less honeycomb structure in the boundaries between calcium metal particles. The composition is heated at least just prior to being extruded into the vessel. The composition upon contacting the molten metal is friable and freely breaks away for rapid reaction with the molten metal. The sodium vaporizes and escapes from the metal serving to cause an agitation of the molten metal bath.
