Physical description & handling notes

• Zinc phosphide is a dark gray granular solid. It is slowly decomposed by water giving off phosphine, a flammable poison gas. It is toxic by ingestion. It is used in medicine and as a rat poison.
• Dark gray crystals or powder with a faint phosphorus or garlic odor; [HSDB]
• DARK GREY CRYSTALS, POWDER OR PASTE WITH CHARACTERISTIC ODOUR.
• Dark gray tetragonal crystals; lustrous or dull powder
• Dark gray, gritty powder
• Amorphous gray-black powder
