Narrow size distribution ground calcium carbonate compositions |
摘要 |
Ground calcium carbonate compositions having narrow particle size distributions and a method for producing the compositions. The method involves forming a substantially dispersant-free calcium carbonate suspension, wet-grinding the suspension, and aging the suspension. The method does not require the use of classification equipment and the aging process does not require heating.
