text: At the time when the carbonation rate reached 15%, 100 g (calculated as the weight of SiO 2 and corresponding to 22 g per 100 g of calcium carbonate formed) of a 20 wt % colloidal silica (in an elongated form having a minor axis of 15 nm and a major axis of 100 nm) solution was added, and the sodium carbonate solution was further fed so as to continue the carbonation reaction, followed by completing the carbonation reaction at the time when the pH of the slurry arrived at 9.
text: At the time when the carbonation rate reached 10%, 100 g (calculated as the weight of SiO 2 and corresponding to 5 g per 100 g of ground calcium carbonate) of a 20 wt % colloidal silica (in an elongated form having a minor axis of 15 nm and a major axis of 100 nm) solution was added, and the sodium carbonate solution was further fed so as to continue the carbonation reaction, followed by completing the carbonation reaction at the time when the pH of the slurry arrived at 9.
