Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate …
Calcite seas existed in Earth history when the primary inorganic precipitate of calcium carbonate in marine waters was low-magnesium calcite (lmc), as opposed to the aragonite and high-magnesium calcite (hmc) precipitated today.
It has a density of 2.71 g/mL and melting point of 1,339 °C, as its calcite form. The other common mineral form, aragonite, has a density of 2.83 g/mL and melting point of 825 °C. Chemical properties: Calcium carbonate is insoluble in water and stable at normal temperatures. When heated to high temperatures, it decomposes to form calcium ...

Precipitated calcium carbonate is a versatile additive for use in a wide range of plastic and elastomeric applications. It's regular and controlled crystalline shape and ultrafine particle size provides our customer with an outstanding cost/performance opportunity.
Calcium carbonate is the active ingredient in agricultural lime, and is created when calcium ions in hard water react with carbonate ions creating limescale. It is commonly used medicinally as a calcium supplement or as an antacid. Precipitated calcium carbonate (PCC) is also a product derived from lime, which has many industrial applications.
The density was measured at 25.2°C (77.36°F or 298.35K) at standard atmospheric pressure. In Imperial or US customary measurement system, the Calcium Carbonate density is equal to 169.2 pound per cubic foot [lb/ft³], or 1.567 ounce per cubic inch [oz/inch³] .

Precipitated Calcium Carbonate is widely used medicinally as an inexpensive dietary calcium supplement or as a gastric antacid. Many medicines contain PCC, as the base material of pills, or for bulking of liquid medicines, ointments or creams. PERSONAL CARE PCCs are used in toothpaste as a viscosity aid and mild abrasive. Other uses include:
Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used; arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive ...
