Description

Strontiumcarbonate CAS NO 1633-55-2 is a white, odorless, and tasteless inorganic salt that serves as a fundamental source of strontium. This compound is valued for its ability to impart unique properties, such as brilliant red color in pyrotechnics and flame retardancy in various materials. It is a critical raw material for manufacturers in the ceramics, electronics, and pyrotechnics industries seeking consistent quality and reliable supply.

Application

• Primary raw material for producing strontium ferrite permanent magnets used in loudspeakers and small DC motors.
• Essential component in the formulation of pyrotechnics and signal flares to produce intense red flames.
• Used in the manufacturing of specialty glasses, including cathode ray tubes (CRTs) and optical glass, to reduce X-ray emission and modify refractive index.
• Acts as a flux and colorant in the production of ceramic glazes and enamels.
• Employed in the electrolytic production of zinc for purifying the electrolyte solution.
• Starting material for the synthesis of other strontium compounds, such as strontium nitrate and strontium chloride.
• Used in the formulation of certain flame-retardant additives for polymers and plastics.
