Phosphide

The new fulminate consists of a mixture of chlorate of potash, with the prussiates, soluble or unsoluble, the hyposulphites, the hypophosphites, the phosphides, the amorphous phosphorus, alone or combined.

These two metals were then melted in magnesia crucibles and cooled slowly, in order to find how much phosphide would separate during solidification.

Colani (1907b) prepared uranium arsenide and antimonide by methods similar to the one he used for the preparation of phosphide.

So you took the bottle of phosphide and you poured a good dose into your sister’s cup.

On the other hand, too much phosphide may render the iron brittle.
