Strontium carbonate

Strontium carbonate (CAS 1633-05-2), also identified under the colorant index reference CI 77837, is an inorganic mineral salt used across ceramics, electronics, and specialty chemical manufacturing.

Where is Strontium carbonate used?

• Electronics: key raw material for cathode ray tube glass
• Ferrite components: controlled strontium content affects dielectric performance
• Coatings: corrosion-inhibiting pigment in anti-rust primers
• Plastics and polymer compounding: heat and light stabilizer in PVC and related systems
• Pharmaceutical and specialty chemical production: catalyst precursor and pH-buffering agent
• It functions as a strontium source in high-temperature processing and as a stabilizing or buffering agent in formulated systems.

Commercial specifications

• Particle size distribution varies by grade, with finer cuts for electronic and coating applications
• Standard packaging ranges from small bags to bulk quantities
