Abstract
Tungsten needles grown from hexacarbonyltungsten vapors in a glow‐discharge condition are described. The needle growth occurs on a tungsten substrate in a temperature range from nearly room temperature to 1500 °K, but needles produced below and above ∼1100 °K are quite different in morphology and crystalline state. The products at lower temperatures are tungsten particles agglomerated in dendritelike shapes while those at higher temperatures possibly are whiskers.Keywords
