摘要

Process for the preparation of prior alloys containing strontium and/or barium which are suitable for the refining of aluminum and silicon alloys, by introducing a compound containing the corresponding alkaline earth metal in a silicon alloy melt at high temperature under vigorous movement of the bath and with joint use of additives, characterized in that a melt of silicon containing at least 0.5% and together with a maximum of 70% magnesium and/or calcium and/or aluminum is reacted, at a temperature of 650 to 1700º c, preferably 1,000 to 1450º c, with a strontium and/or barium compound, and the metal is introduced into the alloy.
