METHOD OF PRODUCING THE AMORPHOUS RED PHOSPHORUS Russian patent published in 1997 - IPC

Abstract RU 2089493 C1

FIELD: chemical technology, inorganic chemistry. SUBSTANCE: high-temperature realloyment of white phosphorus is carried out in the presence of addition taken from the group: graphite, 3MgO•4SiO2•H2O,Al(OH)3,TiO2 and Al2(SiF6)3•Al(OH)3 at amount 0.5-5 wt. -%. For reaction acceleration the process is carried out in the field of ionizing radiation. The obtained red phosphorus exhibits stability to reactions of highly toxic phosphine formation. EFFECT: improved method of producing.
