Abstract: 

In the Co/Si/C system a new CoSi (CsCl type) modification besides ß‐SiC and carbon is observed after a sintering process of the elements at a temperature of 1400 °C (4 h; vacuum). The structure of the cobalt monosilicide (CsCl type) was determined by X‐ray powder diffraction methods and subsequent Rietveld refinement. CoSi (CsCl type) crystallizes in the cubic space group (no. 221) with the lattice parameters a = 281.62(2) pm (V= 22.337(7) × 106 pm3). However, in the Co/Si system only the well known ε‐CoSi (FeSi type) is observed at the same reaction conditions. It is supposed that β‐SiC takes an important role in stabilizing the CoSi (CsCl type). Electron microscopy experiments (SEM and EDX) confirm that the cobalt monosilicide is surrounded by a β‐SiC matrix containing a small amount of carbon. The thermal stability of the synthesized samples was studied. Furthermore, the density of states (DOS) was calculated.
