CADMIUM PHOSPHIDE Usage And Synthesis
Category
Explosive substances
Explosive hazardous characteristics
Reacts with concentrated sulfuric acid to explode
Flammability hazardous characteristics
Thermal decomposition emits toxic phosphorus oxides and cadmium-containing fumes
Storage and transportation characteristics
Warehouse ventilation and low-temperature drying
Fire extinguishing agents
Water, dry powder, foam, carbon dioxide

Preparation method
It can be obtained by passing phosphorus vapor mixed with nitrogen or hydrogen over heated cadmium, or by adding cadmium oxide to a concentrated potassium hydroxide solution to obtain a suspension, then adding a benzene solution of white phosphorus to it, and then boiling it under reflux.
Safety Profile
Confirmed human carcinogen. Explosive reaction with concentrated nitric acid. When heated to decomposition it emits toxic fumes of POx and Cd. See also CADMIUM COMPOUNDS and PHOSPHIDES.
