Uses and synthesis of Strontium carbonate powder

Strontium carbonate powder, formula SrCO3, colorless prismatic crystal or white powder. At 926℃, it is transformed into hexagonal system. The melting point is 1497℃(6.08×106Pa) and the relative density is 3.70. Slightly soluble in water, slightly soluble in saturated solution of carbon dioxide, soluble in ammonium chloride, ammonium nitrate and carbonic acid solution. Strontium carbonate reacts with dilute hydrochloric acid, nitric acid and acetic acid to release carbon dioxide. Strontium carbonate powder is used for the manufacture of color TV cathode ray tubes, electromagnets, strontium ferrites, pyrotechnics, fluorescent glass, signal bombs, etc. It is also a raw material for the production of other strontium salts and is used as the base powder for the production of special PTC thermistor components. Strontium carbonate, as a support of palladium, can be used for hydrogenation. In addition, it is also used in papermaking, medicine, analytical reagents, sugar refining, metal zinc electrolyte refining, strontium salt pigment manufacturing.

Applications/Functions of Strontium carbonate powder

• Strontium carbonate powder is used for the manufacture of color TV cathode ray tubes, electromagnets, strontium ferrites, fireworks, fluorescent glass, signal bombs, etc., and is also a raw material for the production of other strontium salts
• Strontium carbonate is a basic raw material for the production of strontium salt. Glass made of strontium carbonate has a strong ability to absorb X-rays and is commonly used in the production of cathode ray tubes for color television. Also used in electromagnets, strontium ferrites, can be made into small motors, magnetic separators and loudspeakers.
• Strontium carbonate is used as the base powder for the production of nanomaterials, electronic components, fireworks materials, rainbow glass, other strontium salts, PTC thermistor components (switch start, degaussing, current limiting protection, constant temperature heating, etc.)

Physicochemical Property of Strontium carbonate powder

Colorless rhombic system, or fine white powder. Insoluble in water, slightly soluble in ammonia, ammonium carbonate, insoluble in alcohol, easily soluble in ammonium chloride, ammonium nitrate.

Production methodprocess of Strontium carbonate powder

Strontium carbonate powder was prepared by rinsing and drying strontium carbonate powder from underground brine containing bromine and strontium carbonate powder. The bromine extracted strontium mother liquor was neutralized with lime, condensed and cooled, sodium chloride was removed, calcium was removed by caustic soda and ammonium bicarbonate was added to convert strontium hydroxide to precipitate strontium carbonate.
