Abstract Chromium silicide (Cr 3 Si) 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 Cr 3 Si ( a =4.555 A). Transmission electron microscope images indicated that the sample consisted of single-crystalline nanorods with a diameter of 40–80 nm, an average length of about 600 nm and a maximum length of about 1.0 μm. The oxidation of Cr 3 Si 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.

硅化铬（Cr3Si）纳米棒的合成及氧化行为

摘要 以无水三氯化铬和四氯化硅为原料，在 600 °C 高压釜中通过共还原路线成功合成了硅化铬 (Cr 3 Si) 纳米棒。X-射线粉末衍射图表明产物为立方Cr 3 Si(a＝4.555A)。透射电子显微镜图像表明，样品由直径为 40-80 nm、平均长度约为 600 nm、最大长度约为 1.0 μm 的单晶纳米棒组成。Cr 3 Si在空气中650℃开始氧化，但由于形成了保护层，产物在1000℃以下具有较高的热氧化稳定性。
