    Abstract

    Chromium silicide (Cr3Si) nanorods were successfully synthesized using anhydrous chromium trichloride and silicon tetrachloride as starting materials via a co-reduction route at 600°C in an autoclave. X-ray powder diffraction pattern indicated that the product was cubic Cr3Si (a = 4.555 Å). Transmission electron microscope images indicated that the sample consisted of single-crystalline nanorods with a diameter of 40-80nm, an average length of about 600nm and a maximum length of about 1.0μm. The oxidation of Cr3Si began to proceed at the temperature of 650°C in air, but the product had a high thermal oxidation stability below 1000°C due to the formed protective layer.
