How to detect Phosphine
Formula: PH3 | CAS: 7803-51-2
Synonyms: phosphane, hydrogen phosphide, phosphorated hydrogen, phosphorus hydride, phosphorus trihydride
Phosphine is primarily used in the preparation of semiconductors as an n-type dopant for Si semiconductors, and in preparation of GaP and In P devices. it is used as a fumigant in silos.
