METHOD FOR PRODUCING OF COPPER PHOSPHIDE POWDER Russian patent published in 2004 - IPC

Abstract RU 2241053 C1

FIELD: non-iron metallurgy, in particular manufacturing of addition alloy, modifier, solder alloy and past.

SUBSTANCE: Claimed method includes preparation of batch by mixing of copper particles and red phosphorous powder, heating, conditioning and cooling, while batch in reactor is continuously mixed. Heating, conditioning and cooling are carried out in moving closed reactor in the presence of grinding bodies. Temperature of heating and conditioning is lower than eutectic temperature in copper-phosphorous system (namely of 714⁰C).

EFFECT: reduced cost for producing of copper phosphide and environmental acceptability.
