Abstract
PURPOSE: To obtain high purity barium carbonate with a good particle shape contg. little sulfur and alkali, and useful in production of a condenser, a semiconductor, etc. by adding an aq. soln. of barium chloride to an aq. soln. of ammonium hydrogencarbonate in the presence of ammonia followed by reaction.
CONSTITUTION: A below 220 g/l or above 300 g/l aq. soln. of barium chloride is added to a below 270 g/l aq. soln, of ammonium hydrogencarbonate in the presence of ammonia in an amt. above equimolar with the barium chloride, and they are reacted at below 45°C to obtain spherical high purity barium carbonate. The molar ratio of the barium chloride to the ammonium hydrogencarbonate is 0.8W1.2, pref. 1. The ammonia is usually added to the ammonium hydrogencarbonate beforehand, yet it may be added together with the barium chloride.
