  Process for the production of alkaline earth silicides.



   The subject of the invention is a method by means of which the metallic silicides, especially the alkaline earth silicides, can be produced and by which the

     The main advantages are

   high reaction speed and avoidance of the fluidity that the aluminum gives the steel blocks.
