Abstract. Whiskers, having large length/diameter ratio, are fibershaped single crystals. The technical possibility of using calcium carbonate whiskers as papermaking filler to replace conventional powderlike calcium carbonate was investigated. The results showed that it may be feasible to use calcium carbonate whisker as papermaking filler.

Calcium carbonate is the active ingredient in agricultural lime, and is created when Ca ions in hard water react with carbonate ions creating lime scale. It is commonly used medicinally as a calcium supplement or as an antacid. Calcium carbonate is also used in the purification of iron from iron ore in a blast furnace.

Calcium carbonate is the most widely used filler in the plastics industry. Adding calcium carbonate eases the polymer extrusion and also lowers the cost. It enhances the heat resistance, stiffness and hardness of the polymer. Being white in color, calcium carbonate also helps in pigmentation and aids in enhancing or compensating for loss of gloss.
