Calcium Carbonate Whiting Powder

Calcium Carbonate Whiting Powder is a finely milled white mineral powder composed primarily of CaCO3 with a typical purity of at least 95%. It is supplied as a dry, free-flowing powder with particle sizes commonly averaging 2 to 5 microns (D50), facilitating easy dispersion in formulations. Industrial buyers should note its alkaline pH range of 9 to 10 in suspension and minimal moisture content of less than 1%, making it suitable for processes requiring stable pH adjustment and consistent texture. This powder is typically packaged in drums and bags for convenient bulk handling and storage. It is essential to store the material in a cool, dry, well-ventilated environment protected from moisture to maintain quality and prevent clumping or degradation. The chemical is widely employed as a filler, pigment, and processing aid in numerous industrial applications due to its chemical stability, whiteness, and physiochemical properties.

In manufacturing and processing operations, maintaining consistent product properties and cost control are critical. Calcium Carbonate Whiting Powder addresses these needs by acting as an inert filler that improves whiteness and opacity in paints and coatings, enhancing product appearance while reducing pigment requirements. Additionally, in water treatment, it plays a vital role in neutralizing acidity, preventing corrosion and scaling in equipment. Its capacity to adjust pH precisely helps maintain process stability and extends equipment life, minimizing downtime and maintenance costs.
