Strontium carbonate

    Strontium carbonate is an important alkaline earth metal carbonate with the chemical formula SrCO and a molecular weight of

147.63 g/mol. At room temperature, it appears as a white, odorless powder with a density of 3.5 g/cm³ and a decomposition tem-

perature of 1497°C. Naturally occurring as strontianite, industrial-grade products typically have a purity of ≥97.5%. Its unique

chemical properties make it an indispensable functional additive in the ceramic industry.

Product features:

·Fluxing Agent: The decomposition product SrO significantly lowers the melting point of glazes (by 50-100°C).

·Expansion Control: Effectively adjusts the thermal expansion coefficient of glazes (reduction of 15-20%).

·Optical Properties:

    oEnhances glaze gloss (increase of 10-15 GU).

    oPromotes special optical effects (iridescence, opalescence, etc.).

·Crystallization Promoter: Acts as a nucleating agent for strontium silicate crystal formation.
