Calcium carbonate powder is a finely ground, white or off-white powder that is commonly used in a wide range of applications, including construction, manufacturing, and pharmaceuticals. With a chemical formula of CaCO3, calcium carbonate is a naturally occurring mineral that is found in limestone, chalk, and marble. The powder is produced by grinding and classifying high-purity limestone or other calcium carbonate-rich materials into a fine powder, typically with a particle size of less than 10 microns.
The production process for calcium carbonate powder involves several stages, including mining, crushing, grinding, and classification. The resulting powder is highly versatile and can be used in a variety of applications, including as a filler, coating, or abrasive. Calcium carbonate powder is also used as a dietary supplement, as it is an excellent source of calcium, which is essential for maintaining strong bones and teeth.
In terms of its chemical properties, calcium carbonate powder is a relatively stable compound that is insoluble in water but soluble in acids. It has a melting point of around 800°C and a density of approximately 2.7 g/cm3. The powder is also non-toxic and non-corrosive, making it a popular choice for use in a wide range of industries, from food and pharmaceuticals to construction and manufacturing.
