Description

Strontium Carbonate CAS NO 1633-05-2 is an inorganic salt of strontium and carbonic acid, appearing as a white, odorless powder. It is a critical industrial material valued for its ability to impart unique properties, most notably a brilliant red flame colorant in pyrotechnics and a high refractive index in specialty glass. This compound is essential for manufacturers in the electronics, ceramics, and chemical synthesis sectors seeking consistent quality and reliable supply for their core processes.

Application

• Pyrotechnics and Signal Flares: Primary application as a red colorant in fireworks, marine distress signals, and military tracers.
• Electronics Manufacturing: Key component in the production of ferrite magnets for loudspeakers, small DC motors, and microwave devices.
• Specialty Glass and CRT Production: Used to increase the refractive index and X-ray absorption in optical glass, television faceplate glass, and cathode ray tubes.
• Ceramics and Glazes: Imparts durability and acts as a flux in ceramic glazes, tiles, and permanent ceramic ferrite magnets.
• Chemical Synthesis: Serves as a precursor for other strontium compounds, such as strontium nitrate and strontium chloride.
• Electrolyte Production: Used in the manufacturing of electrolytic zinc for purification and refining processes.
• Sugar Refining: Employed in certain processes for the purification of beet sugar.
