Abstract

In a method of preparing alloys of aluminium and calcium in which an oxygen-containing compound, other than a sulphate or oxyhalide, of calcium is heated in a bath of molten aluminium, the slag which is formed in addition to the alloy may be used for the preparation of cements such as those known under the Registered Trade Mark "Ciment Fondu."ALSO:Aluminium alloys containing alkaline earth metals are made by heating in a bath of molten aluminium an oxygen-containing compound, other than a sulphate or an oxy-halide, of an alkaline earth metal at such a temperature, for example 1350-1600 DEG C., that in addition to the desired alloy a molten slag is formed. In the case of magnesium, barium, or strontium compounds, calcium aluminate may be added to the charge in order to make the slag sufficiently molten. The process may be operated continuously by tapping off the aluminium alloy and some of the slag from time to time, and adding a further charge of starting materials. In the case of magnesium, the process may be carried out in a closed furnace and means provided for condensing the evolved magnesium and aluminium vapours. In the case of calcium, the slag may be used for the preparation of cements such as those known under the Registered Trade Mark "Ciment Fondu."
