Description

Strontium CAS NO 7440-24-6 is a soft, silvery-white alkaline earth metal with significant reactivity. It is valued for its unique chemical and physical properties, particularly its ability to produce a brilliant red color in pyrotechnic compositions and flares. This element is essential for manufacturers in the pyrotechnics, metallurgy, and electronics industries, where it is used as an alloying agent and in specialized glass for cathode ray tubes.

Application

• Pyrotechnics and Signal Flares: A key component for producing intense red flames and colors in fireworks and emergency signals.
• Ferrite Magnet Production: Used in the manufacturing of strontium ferrite permanent magnets for electric motors and loudspeakers.
• Aluminum Alloy Refinement: Acts as a modifying agent in aluminum-silicon casting alloys to improve mechanical properties.
• Electronics and Vacuum Tubes: Employed as a getter to remove residual gases in vacuum tubes and certain electronic components.
• Specialty Glass and Ceramics: Imparts specific optical and electrical properties to glasses and ceramic glazes.
• Medical Research: Strontium-89 and Strontium-90 isotopes are used in radiotherapy for bone cancer and as radioactive tracers.
• Chemical Synthesis: Serves as a precursor or catalyst in various organic and inorganic synthesis processes.

Quality Control

Our strontium metal is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay and trace metal impurities. Our quality management system is designed to meet the rigorous demands of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive nature, strontium metal must be stored under an inert atmosphere such as argon or mineral oil to prevent oxidation and reaction with moisture. Store in a cool, dry, well-ventilated area away from incompatible materials like acids and oxidizers. Keep the container sealed when not in use.
