Product Description

Strontium carbonate powder CAS NO 1633-05-2 was used in making special glass and ceramic glazes



  Strontium carbonate (SrCO3) is a white, odorless, tasteless powder. It is the


carbonate salt of strontium that has the appearance of a white or grey powder. It


occurs in nature as the mineral strontianite.

        Strontium carbonate is often recommended as a substitute for barium to


produce matte glazes. Use about 75% as much and test first to make sure color


response is the same. However strontium is not a substitute for barium as a


precipitator of soluble salts in clay bodies because it combines with SO4-- ions in


the water to form a compound that is not nearly as insoluble as BaSO4.Viscous


zirconium silicate glazes can be smoothed with the addition of strontium carbonate.

         Strontium is considered a safe material. Some people confuse SrO with


Strontium 90, an isotope released from atomic reactions; they are not the same



          As noted, strontium carbonate produces gases as it decomposes and these


can cause pinholes or blisters in glazes (if they are being generated into a glaze


melt having a viscosity and surface tension that is unable to pass them or heal over


properly as they escape or one that simply does not have time because of quick


cooling). There are many strontium frits available and incorporating one of them to


source the SrO instead of raw strontium carbonate (a classic job for glaze


chemistry calculations). The resultant glaze will be more fusible and will have better


clarity and fewer defects. Strontium frits have become much more common of late


and are useful to producing brilliant transparent glazes without having a high


expansion (like those based on Na2O and K2O). Please read the information about


the oxide SrO to fully appreciate the value of SrO frits, not just as alternatives to


this material, but as excellent ways to produce brilliant glazes.
