The ignition of iron nanopowders of bulk density and those compacted to a relative density of 0.3–0.5 during heating in air has been studied. The ignition temperature of the compacted samples is independent of the heating rate and is 100–115°C. The durations of the active stages—ignition and filtration combustion—under identical heating mode depend on the sample density, which makes it possible to develop methods to store iron nanopowders in the compacted state.

铁纳米粉的密度对其在空气中加热过程中点火参数的影响

已经研究了体积密度的铁纳米粉末和那些在空气中加热过程中压实到 0.3-0.5 的相对密度的铁纳米粉末的点火。压实样品的着火温度与加热速率无关,为 100-115°C。在相同加热模式下,活跃阶段(点火和过滤燃烧)的持续时间取决于样品密度,这使得开发以压实状态存储铁纳米粉末的方法成为可能。
