Abstract Metallic W whiskers with tip diameters of 50–250 nm and lengths of 2–4 µm have been successfully synthesized in large quantities using Co–Ni alloyed catalysts. The relatively low growth temperature of 850 °C and the large catalyst size (over 100 nm) suggest that the growth of the W whiskers must be governed by the vapor–solid–solid mechanism. Our results show that the vapor–solid–solid model is suitable not only for the growth of nano-scaled whiskers with diameters below 100 nm, but also for submicro-scaled whiskers with diameters well above 100 nm. This technique has great potential to synthesize well controlled metallic whiskers.
