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.
