Precipitated calcium carbonate (PCC) is widely used as a filler and a pigment in various applications, e.g. in paper, plastics and pharmaceutics (Roskill Information Services, 2012, Stratton, 2012).The main PCC production method is the so-called carbonation process, in which limestone (CaCO 3) is first calcined in a lime kiln to …

Wet granulation process was used to prepare the Calcium Carbonate and vitamin D3 tablets by using different types of excipients (table 1). Tablet properties were evaluated by performing various tests. The result of weight variation test was + 0.76% and -1.42%. The weight variation test is alternative to content uniformity test that assure the

 — Calcium carbonate manufacturing process. Posted: 2020-01-07. Calcium carbonate is usually divided into heavy calcium carbonate/ ground calcium carbonate powder and light calcium carbonate/ precipitated calcium carbonate. Heavy calcium carbonate is also called ground calcium carbonate, referred to as heavy calcium …

 — A classic example is calcium carbonate, the most widely used form of calcium. In a normal tablet or powder, the calcium carbonate dissolves in the stomach acid and is carried into the digestive system for absorption. As the calcium carbonate dissolves, however, it releases carbon dioxide, resulting in stomach gas.
