A method for dephosphorizing a manganese containing melt is disclosed. The method encompasses the addition of a magnesium compound to a manganese containing melt to form magnesium phosphides which are removed from the melt. The method is carried out under pressure and the addition of a flux in the melt is employed to facilitate the removal of the phosphides from the melt.

Dephosphorization process for manganese-containing alloys

A copper catalyzed silicon reaction mass for the production of methylchlorosilane which comprises free-flowing powders or particles of silicon metal having spots of a copper-silicon alloy substantially uniformly distributed on the surface of the silicon particles, the copper constituting less than about 2% and preferably about 1.75% by weight of the catalytic mass.

Preparation of reaction mass for the production of methylchlorosilane

Vanadium-carbon materials for use as additions to steel have been produced by the vacuum furnacing of a mixture of vanadium oxide and carbon. To lower the sulfur content of such material, which derives essentially from the sulfur content of the carbon in the mixture, a relatively small quantity of silicon, silica or tin is included in the mixture prior to vacuum furnacing.

Process for lowering the sulfur content of vanadium-carbon materials

A vessel in which molten metal is stirred is provided with an interior configuration which prevents the formation of a vortex in the stirred metal thereby reducing the surface area of the metal.

Method for admixing solids in molten metal

Addition of strontium to silicon or ferrosilicon using a mixture containing carbon and at least one material selected from the group of strontium oxide, and strontium carbonate and strontium sulfate.
