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:

PRECIPITATED CALCIUM CARBONATE (PCC) Composition: Most PCC added to the wet end of paper machines consists almost entirely of the calcite crystal form of CaCO 3. The calcite crystal can have several different macroscopic shapes. These depend on the conditions of production. The most economical way to get PCC at a paper mill requires a satellite ...

The current high global demand for high-quality paper, paint, adhesive/sealant, and plastic, filler industries cannot survive without unique and high-quality precipitated calcium carbonate (PCC). They are used as fillers, additives, and reinforcements. PCC is a key constituent of the modern paper and plastic industry. This article reports the effect of various organic and inorganic additives ...

Precipitated calcium carbonate is produced using the most economic process existing today. Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900°C. To ensure a high level of purity, the calcination process is carried out using natural gas.

The precipitate is calcium carbonate, which is chalk and is also in eggshells, seashells, and coral. Looking at the chemical equation, the products are calcium carbonate, sodium chloride, water, and carbon dioxide. Carbon dioxide leaves the reaction as a gas and sodium chloride dissolves in the water, so the precipitate must be calcium carbonate.
