Uses and applications
What the substance is used for, by industry and function
In the production of lead batteries two antimony compounds occur: in the casting of grids antimony trioxide (Sb2O3), and in the formation of lead plates stibine (SbH3).
High purity stibine is used as an n-type, gas-phase dopant for silicon in semiconductors.
Used as a fumigating agent.
Industries and functions
How it is made
Stibine may be prepared by the treatment of metal antimonides with acid, chemical reduction of antimony compounds, and the electrolysis of acid or alkaline solutions using a metallic antimony cathode.
Prepared by dissolving zinc-antimony or magnesium-antimony alloy in dilute (hydrochloric acid). ... Preparation of the alloy from powdered antimony and magnesium...
