Abstract

The present invention is related to the methods of manufacture of single-phase aragonite by controlling calcium ions, particularly, to the methods of manufacture of single-phase aragonite in the solution process by controlling the rate of elution of calcium ions in the suspension of calcium hydroxide by adding the highly concentrated aqueous solution of sodium hydroxide to the suspension of calcium hydroxide and adding the aqueous solution of sodium carbonate to the above mixed aqueous solution at a constant rate. The method of manufacture of single-phase aragonite according to the present invention is characterized by containing no calcite practically since this method is comprised of the steps of manufacturing a suspension in which calcium hydroxide is dispersed in distilled water; controlling calcium ions in the suspension of calcium hydroxide by adding the aqueous solution of sodium hydroxide to the suspension; and supplying the aqueous solution of sodium carbonate at a constant rate while stirring the suspension of calcium hydroxide.
