Abstract

Desensitized free-flowing red phosphorus. The phosphorus is comprised of a homogeneous blend consisting of between about 80 and 98 weight% of red phosphorus having a particle size of up to about 2 mm, and of between about 2 and 20 weight% of an organic or organo-silicon compound desensitizer. The desensitizer is liquid, inactive with respect to red phosphorus and has a minor vapor pressure at room temperature at atmospheric pressure.
