Chemical reagent preparation of strontium carbonate

strontium carbonate chemical reagent method basically has the following two kinds:

1. Number one. Hydrogen strontium oxide soluble in water, filtered to remove impurities. In a transparent solution into carbon dioxide, until no longer precipitation precipitation. Will be careful of suspension of heating and heat preservation for a period of time, in order to make the acid dissolved type strontium carbonate decomposition and form larger particles strontium carbonate precipitation, suction, in 200 ~ 250 ℃ dry, the finished product. The yield of about 100%. Reaction is as follows:

the Sr ( 哦) Twenty our fleet & rarr; SrCO3 ten H20

(2) the number two. Will l00g strontium nitrate dissolved in 500 ml hot water, under stirring slowly add 120 g ammonium carbonate, and then on the water bath heating generated precipitation aging. With leaching precipitation funnel, use a small amount of water until no nitrate, at 110 ℃ in dry. Strontium carbonate 70 g, yield of 95%. The reaction is as follows:

the Sr ( N03) 2 + ( NH4) 2C03→ SrC03 + 2 nh4no
