Abstract
Small rotund salt-coated magnesium (or Mg alloy) granules, useful as an inoculant material or additive for molten metals, are prepared by adding a boron-containing dispersing agent to a molten salt mixture containing molten magnesium (or Mg alloy) stirring to effect good dispersion, and cooling the molten mixture to effect freezing of the magnesium as small rotund globules dispersed in a solid friable matrix. The frozen salt matrix is then pulverized to release the magnesium globules from the matrix, said globules still carrying a beneficial coating of the salt material.
