Strontium carbonate is used in the production of glass, colour formation pieces in TVs and pigments as a magnetic part.
Strontium carbonate (SrCO3) and barium carbonate (BaCO3) are among the materials that are widely used in various industries.
For the calcium carbonate of scale, iron and strontium carbonate were analyzed: calcium carbonate is 90%, strontium carbonate is 3%, sand is 3%, and the others are 3% (including the oil which is not washed).
I had prepared large 'cigars' filled with salt, soda ash, copper carbonate, strontium carbonate, wood ash and sawdust, which I would introduce into the kiln towards the end of the firing.
In the next analytical step strontium carbonate was separated from calcium carbonate with 65% [HNO.sub.3].
Summary: In present study, strontium carbonate of high purity (99.96 %) was synthesized by developing a simple and economically viable process, on treatment of 25-30% higher than stoichiometric ratio of Na2CO3 with upgraded strontium ore at 90oC for a duration of 90 minutes.
Stable strontium is readily available in many safe forms, including strontium citrate and strontium carbonate.
found that pyrotechnical light, a form of the flash pot mentioned above, was shown to contain the similar products Nitrocellulose and Ammonium Perchlorate (N[H.sub.4]C1[O.sub.4]) in addition to Potassium Perchlorate (KCl[O.sub.4]), Strontium Carbonate (SrC[O.sub.3])), Magnesium (Mg), and Shellac.
But I have read that strontium citrate and strontium carbonate are toxic, and the doses sold in stores are too high.
Recent analyses of strontium carbonate standard SRM 987 yield [sup.87]Sr/[sup.86]Sr = 0.710245?0.000018 (2o).
