実験手順
Another production method for strontium carbonate entails reacting the naturally occurring strontium sulfate with sodium carbonate in aqueous solution to form sodium sulfate and strontium carbonate. The sodium sulfate has a much higher solubility in water than strontium carbonate, so filtration and washing will yield a solid strontium carbonate essentially free of sodium sulfate. Once again, this method yields a fine, fluffy, low bulk density powder which is not free flowing.
