Figure 3

Schematic illustration of the growth mechanism. (1) 4CrCl3(g) + 11Si(s) → 4CrSi2(s) + 3SiCl4(g); 4SiCl4(g) + 2CrCl3(g) → 2CrSi2(l) + 11Cl2(g). (2) Growth of CrSi2 particles and nanowires. (3) High-density CrSi2 nanowires. (I) 10CrCl3(g) + 12Si(s) + 3H2(g) → 2Cr5Si3(s) + 6SiCl4(g) + 6HCl(g). (II) Growth of Cr5Si3 nanowires.
