摘要：

The present invention relates to a process for producing a surface-treated calcium carbonate with improved stability in environments with a pH of 4.5 to 7, wherein calcium carbonate, at least one acid having a pKa value from 0 to 8, when measured at 20° C., and at least one conjugate base are brought into contact to form surface-treated calcium carbonate.
