Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

The product is chemically stable under standard ambient conditions (room temperature).

Reactivity

No data available

Hazardous reactions

Risk of explosion with: Powdered metals, aluminium oxide, boron phosphide, Cyanides, Acetic anhydride, sodium phosphite, sodium thiosulphate, performic acid, sulfur, Polyvinyl chloride. Risk of ignition or formation of inflammable gases or vapours with: Risk of explosion with: organic combustible substances, oxidisable substances, carbon, Arsenic oxides

Avoid

Fusion of mixtures of metal cyanides, including lead thiocyanate, with metal chlorates, perchlorates, nitrates or nitrites causes a violent explosion. Addition of one solid component (even as a residue in small amount) to another molten component is also highly dangerous. Heat. no information available
