Description

General description

Strontium carbonate is a weak base widely used as a starting material in the manufacture of glass cathode ray tubes, colorants in fireworks, phosphors for electroluminescent devices, superconductors, and various Sr-based compounds. It can also be used as a cocatalyst in photocatalytic composites, to expand their photoresponsive range.

Application

Strontium carbonate can be used as a precursor to:

• Fabricate ceramic composites for n-type thermoelectrics such as SrTiO₃–TiO₂.
• Prepare SrCO₃/SrO systems for thermochemical energy storage application.
