Stabilized red phosphorus

摘要

The invention provides stabilized pulverulent red phosphorus comprising a homogeneous blend of red phosphorus particles with a size of at most about 2 mm, aluminum hydroxide and a further metal hydroxide as oxidation stabilizers, wherein the metal hydroxide is lead hydroxide. The homogeneous blend contains aluminum hydroxide and lead hydroxide in a total proportion of about 0.1 to 6 weight %, based on the quantity of red phosphorus, the aluminum hydroxide and lead hydroxide, calculated as Al2O3 to PbO, being used in a quantitative ratio of about 0.5 to 2.0.
