Description

Application

• Strontium carbonate: Extensively used in the production of glazes in ceramics, where it acts as a flux and introduces strontium into the glaze for improved finish and durability. It is also crucial in the manufacture of ferrite magnets, providing the necessary strontium content to enhance magnetic properties. Additionally, its role in pyrotechnics is to contribute to the vibrant red hues seen in fireworks displays (Sigma-Aldrich, CAS 1633-05-2).
