Strontium Carbonate powder is a kind of chemical formula SrCO₃ white tasteless and odorless powder, insoluble in water, can be used in electronics, ceramics, pyrotechnics and other fields.
Properties
Chemical formula: SrCO₃
Molecular weight: 147.63
CAS No.: 1633-05-2
Appearance: white powder, odorless and tasteless.
Density: about 3.7 g/cm³.
Melting point: 1497°C.
Solubility: insoluble in water, slightly soluble in carbon dioxide-containing water and ammonium salt solution, soluble in dilute hydrochloric acid and dilute nitric acid and other acid solutions, and release carbon dioxide gas.
Stability: stable at room temperature and pressure, but will decompose into strontium oxide and carbon dioxide at high temperature.
Applications
Electronic industry: It is an important raw material for color picture tubes, magnetic materials, etc. It is used in the manufacture of cathode ray tube glass and phosphor in electronic components, which can improve the performance and display effect of electronic devices.
Ceramic industry: Strontium Carbonate is used as a flux for ceramic glaze, which can lower the melting point of the glaze, improve the gloss and texture of the glaze, and make the ceramic products more beautiful and durable. At the same time, it can also be used in the manufacture of special ceramics, such as piezoelectric ceramics, thermal ceramics, etc., giving ceramics special electrical and thermal properties.
Fireworks manufacturing: adding strontium carbonate powder to fireworks can make the flame show bright red color and increase the ornamental effect of fireworks.
Chemical industry: It can be used as a carrier for catalysts, desulfurizers, etc., to improve the activity and stability of catalysts, as well as for the removal of sulfur dioxide and other harmful gases in industrial waste gas.
Pharmaceutical field: It can be used as pharmaceutical intermediates for the synthesis of certain drugs, and can also be used as a desensitizer in toothpaste and other oral care products to alleviate the symptoms of tooth sensitivity.
Building materials industry: added to cement, it can improve the early strength and abrasion resistance of cement and improve the performance of cement.
