Abstract

Prepn. of fine powders of simple metal silicides or of solid solns. of solicides of gps. IVa, Va, VIa and VIII transition metal silicides by redn. of a cpd. (pref. a sulphide or mixt. of sulphides) of these metals in contact with a reducing agent (H2) and a cpd. capable of liberating Si pref. a chlorosilane at a temp of 300-900 degrees C is used for 1-10 hrs. Prior to completion of the reaction, it may be interrupted and the excess sulphide removed by a selective reaction with sodium or potassium bromate. The reactions can be carried out at much lower temps. than in prior art.
