実験手順

As shown in FIG. 1, a 0.025M strontium hydroxide (Sr(OH)2) suspension as a metal ion source was mixed in a container with a 0.5M urea ((NH2)2CO) aqueous solution as a carbonate ion source to prepare a mixture solution. The pH of the mixture solution was 12.60. The container having the mixture solution was placed into a reaction vessel and held at 90° C. for 120 minutes while agitating the mixture, whereby thermal decomposition of urea (heating reaction) occurred to produce strontium carbonate crystals as the foregoing carbonate particles. The pH of the liquid after heating reaction, measured at room temperature (25° C.), was reduced to 11.50. The agitation was conducted at 500 rpm.
