description Product Description
Used extensively as a filler in the production of paper, plastics, and paints to improve texture, opacity, and durability. In the food industry, it serves as a calcium supplement and anti-caking agent in products like baking powder and cereals. It is also employed in pharmaceuticals as an active ingredient in antacids and calcium tablets. In construction, it acts as a raw material in cement and as a coating pigment in wall paints. Additionally, it is utilized in environmental applications for water treatment to neutralize acidic conditions.
