At NINGBO INNO PHARMCHEM CO.,LTD., we believe that understanding the fundamental aspects of our chemical products is crucial for our clients. This article focuses on Strontium Carbonate (SrCO3, CAS 1633-05-2), detailing its key chemical properties and the primary manufacturing processes involved.

Strontium Carbonate is an inorganic compound characterized by its appearance as a white or grey powder. It is practically insoluble in water but readily dissolves in acids, releasing carbon dioxide gas. This reactivity with acids is a fundamental chemical property that makes it useful as a precursor for synthesizing other strontium compounds, such as strontium chloride or strontium nitrate. The chemical formula SrCO3 signifies its composition of strontium cations (Sr²⁺) and carbonate anions (CO₃²⁻).

The production of Strontium Carbonate typically starts with celestite, a mineral form of strontium sulfate (SrSO4). Two main synthetic routes are employed:

1. The Black Ash Process: In this method, celestite is roasted with a reducing agent, commonly coke, at high temperatures (1100-1300 °C). This process converts strontium sulfate into strontium sulfide (SrS). The resulting strontium sulfide is then reacted with carbon dioxide or sodium carbonate in an aqueous solution to precipitate Strontium Carbonate. This is a widely used commercial method for strontium carbonate manufacturing.
2. The Direct Conversion (Double Decomposition) Method: This approach involves treating purified celestite ore directly with sodium carbonate or ammonium carbonate in a slurry. Alternatively, the purified ore can be dissolved in hydrochloric acid to form strontium chloride, which is then reacted with sodium carbonate to precipitate Strontium Carbonate.

The choice of manufacturing process can influence the purity and particle size of the final Strontium Carbonate product, which are critical parameters for various strontium carbonate industrial applications. NINGBO INNO PHARMCHEM CO.,LTD. focuses on producing high-purity Strontium Carbonate to meet the stringent demands of industries like electronics and pharmaceuticals.
