Abstract : The growth mechanism of iron whiskers produced by the hydrogen reduction of iron halide salts was investigated by the variation of a number of parameters. The observations are correlated with current theories and with the thermodynamic behavior of this reaction which indicates that the tip of the growing whisker should be colder than the ambient medium (the cold tip). The mass growth of iron whiskers in the presence of carbon was examined to evaluate the potential of this method to produce marketable whiskers. An unidentified, nonmetallic whisker growth was discovered growing in bone charcoal. Growth was determined to require the presence of a ferrous halide and calcium orthophosphate. Further postulates concerning the cool tip theory are made. (Author)
