This paper describes a novel way to prepare the ternary phase Ti 3 SiC 2 in a single‐step procedure that we call electron‐beam‐ignited solid‐state reaction (EBI‐SSR). The preparation route is discussed by means of an isothermal section of the Ti‐Si‐C phase diagram. Properties such as the Vickers hardness and the electrical resistivity of the resulting samples are presented. Our property data compare well to those that have been published. The main advantages of this preparation method are the controllability of process parameters such as heating rates, temperatures, and times, as well as the short duration of the overall sample preparation. However, a disadvantage is the presence of second phases (typically in amounts of <8%) that must be reduced via further optimization of the process.
