Cuprous potassium cyanide Specification

Cuprous potassium cyanide , its CAS NO. is 13682-73-0, the synonyms are Cuprate(1-), dicyano-, potassium ; Potassium dicyanocuprate(1-) . It is an inorganic cyanide. Members of this class that contain heavy metals tend to explosive instability, most of them are capable of violent oxidation under certain condition; fusion of metal cyanides with metal chlorates, perchlorates, nitrates or nitrites can cause violent explosions
