The macroscopic shape of the starting material is retained during the solid/gas reaction between iron and gaseous SiCl 4 , which leads to the formation of iron silicide FeSi (as well as FeCl 2 , which is gaseous under the reaction conditions (1000°C)): If, for example, an iron wire spiral (see bottom of picture) is used, the reaction product FeSi also retains this spiral form (top).
