ABSTRACT:
A product and method of manufacture are set forth. The product is used in desulfurizing steel. Magnesium is in its molten state, and with vigorous stirring, lime is added. A relatively brittle material is obtained upon cooling which can be ground to a particulate form and used in steel desulfurization. The composite is both a mixture of magnesium and lime and also includes Mg.sub.2 Ca alloy.
