Abstract
PURPOSE:To obtain the title carbonate capable of providing a calcined product having a uniform composition and appropriate for the production of electronic device materials, etc., by allowing two kinds of the water-soluble compds. of alkaline-earth metals selected from Ba, Sr, and Ca to react with more than the equivalent of a water-soluble carbonate. CONSTITUTION:(A) The two kinds of the water-soluble compds. of alkaline-earth metals selected from Ba, Sr, and Ca (e.g., barium chloride and strontium chloride) are allowed to react with (B) a water-soluble carbonate (e.g., sodium carbonate) in an aq. soln. so that the carbonate radical of the B component is controlled to $1i equivalent, based on the total amt. of the A components. The formed precipitate is filtered, washed with water, and then dried. By this method, the carbonates of alkaline-earth metals shown by formulas I, II, and III are obtained [(x), (y), and (z) are respectively >=0.1, (x+y)=1, (x+z)=1, and (y+z)=1]. The compds. are appropriately used for the production of barium strontium ferrite, etc.
