A composition of matter comprising a mass of ferrous scrap pieces compressed together in random orientation forming a network of interlocking pieces has been prepared. The ferrous metal network has a density of 1.2 to 6.3 g/cc, a porosity of 20% to 85%, and a short transverse tensile strength (S.T.T.S.) of at least 2.0 psi, preferably at least 2.5 psi. This ferrous metal network may be impregnated with magnesium in amount from 5% to 55% by weight of the impregnated body. The magnesium impregnated body is useful for treating high melting metals, such as ferrous metal to reduce the sulphur content and to produce nodular form.

Ferrous metal network impregnated with magnesium metal

A composition of matter comprising a mass of ferrous scrap pieces compressed together in random orientation forming a network of interlocking pieces has been prepared. This ferrous metal network is impregnated with rare earth metals in amount from 15% to 80% by weight of the impregnated body. The rare earth metal impregnated body is useful for treating high melting metals, particularly to deoxidize or desulfurize steel and to produce nodular iron.

Ferrous metal network impregnated with rare earth metals

A composition of matter comprising a mass of ferrous scrap pieces compressed together in random orientation forming a network of interlocking pieces has been prepared. The ferrous metal network has a density of 1.2 to 4.0 g/cc, a porosity of 50% to 85% and a short transverse tensile strength (S.T.T.S.) of at least 2 psi, preferably at least 2.5 psi. This ferrous metal network may be impregnated with magnesium in amount from 18 to 55% by weight of the impregnated body. The magnesium impregnated body is useful for treating high melting metals such as ferrous metal to reduce the sulphur content or to produce nodular iron.
