挥发性金属如锌1，2和镉2，3的晶须是通过蒸汽冷凝法生长的;但其他金属的晶须大多是通过化学还原法生产的4，5。铝是一个特殊的问题，因为它的化合物是抗还原的，而且在熔点时的蒸汽压非常小（外推1.0 × 10− 43毫米）。汞）。在较高的温度下，当蒸汽压较大时，金属的反应性极强，甚至与氧化铝接触也会形成低价氧化物。本文报道的工作表明，利用高过饱和度的蒸汽冷凝法生产铝晶须是可能的。
WHISKERS of volatile metals such as zinc1,2and cadmium2,3have been grown by vapour condensation methods; but whiskers of other metals have mostly been produced by chemical reduction4,5. Aluminium presents particular problems because its compounds are resistant to reduction and because the vapour pressure at its melting point is very small (by extrapolation 1.0 × 10−43mm. mercury). At higher temperatures where there is an appreciable vapour pressure the metal is extremely reactive, and even contact with alumina leads to the formation of a sub-oxide. The work reported here shows that it is nevertheless possible to produce aluminium whiskers by a vapour condensation method using high supersaturations.
