ABSTRACT

The industrial importance of calcium carbonate as a filler in composite materials such as
plastics, textiles, rubbers, paints, pigments and paper is well recognized and the
application in the polymer industry is increasing. Therefore, surface modification is a
key process in functional calcium carbonate powder preperation. In this study, surface
modification of calcium carbonate particles, obtained Niğde region, using sodium
stearate (SDS) and sodium oleate (SO) as modification agents incorporated with the
simultaneous wet ultra-fine grinding in the laboratory horizontal stirred mill was
investigated. The results indicate that the hydrophilic surface of calcium carbonate is
turned into hydrophobic after modification with the reagents.

Keywords: Calcium carbonate; surface modification; horizontal stirred mill
