Anwendungen

Strontium nitrate is used in the production of road flares and in fireworks. It serves as a colorant (red) in pyrotechnics and is also used as an oxidizer in pyrotechnics. Mixed with glycolic acid, it is used to reduce the sensation of skin irritation. It is also used in electrophysiology experiments.

Bemerkungen

Hygroscopic. Incompatible with strong reducing agents, strong acids.
