Abstract
The method consists in subjecting a mixture of an alkali nitride and/or an alkaline-earth nitride to thermal decomposition in vacuo in the presence of at least one metallic component with which it is desired to alloy the alkali metal and/or the alkaline-earth metal, the metals thus brought together are melted and the alloy thus obtained is homogenized.
Claims17
A method of producing an alloy containing an alkali metal, an alkali-earth metal and a metal co-component alloyable therewith, comprising:
- confining at least one alkali metal nitride, at least one alkali-earth metal nitride and at least one metallic co-component of the alloy to be formed in a reaction chamber;
- thermally decomposing, substantially in a vacuum, said alkali metal nitride and said alkali-earth metal nitride in said chamber to a mixture of said alkali and alkali-earth metals, and
- melting said mixture of metals thereby forming a substantially homogeneous alloy.
A method of producing an alloy containing at least one metal selected from the group consisting of alkali metals and alkali-earth metals, and an additonal metal co-component;
- confining at least one nitride selected from the group consisting of alkali metal nitrides and alkali-earth metal nitrides in a reaction chamber with the additional metal co-component alloyable with said metals;
- and
- thermally decomposing in a vacuum, said nitride to its component metal and nitrogen;
- and
- melting the resultant mixture of metals thereby forming a substantially homogeneous alloy.
