Abstract
Alloys of calcium and silicon with one or more of zirconium, aluminium, barium, lithium, beryllium, magnesium, and containing less than 7% of iron, are produced by adding a compound of the metal preferably oxide, silicate or carbonate, either before or during the manufacture of the calcium-silicon alloy in an electric furnace, while similar calcium-silicon alloys but containing one or more of potassium, sodium, titanium or cerium are obtained by adding compounds of those metals to a bath of molten calcium-silicon alloy. That part of the final alloy other than the added metal or metals preferably contains 20-35% calcium, 55-65% silicon, 2-7% iron and less than 1% carbon, and the proportion of added metal may be 0.1-30% of the total of those constituents. Alloys particularly referred to are those containing 5-30% magnesium, 0.5-15% sodium or 0.1-3% cerium for nodularizing cast irons, 2-15% titanium for inoculating cast irons, and 2-20% aluminium for refining low carbon ferrous metals. In an exemplified process, calcium carbide, magnesium carbonate, quartz, charcoal and coke are heated together in an arc furnace.
