Product Details
Strontium carbonate (SrCO₃, CAS 1633-05-2) is a strontium salt of carbonic acid, naturally found as the mineral strontianite. It is widely used in industry, most notably as a cost-effective red-emitting agent in pyrotechnics. When heated during combustion, strontium ions produce a vivid crimson flame, making it especially valuable for fireworks formulations.
