STABILIZED AND DESENSITIZED FLOWABLE RED PHOSPHORUS Stabilized and desensitized pulverulent flowable red phosphorus consisting of particles with a size of at most 2 mm, and process for making it. To this end, red phosphorus is prepared from yellow phosphorus. Next, an aqueous suspension of pulverulent red phosphorus is freed from residual fractions of yellow phosphorus by treating it with a sodium hydroxide solution, and the red phosphorus in the aqueous suspension is stabilized with aluminum hydroxide and a hardened epoxide resin and desensitized in the aqueous suspension by means of a water-emulsifiable organic compound which is liquid, inactive with respect to phosphorus and has a low vapor pressure at room temperature and at atmospheric pressure. |
