Calcium Carbonate (CaCO3)

Calcium carbonate can also be an additive to food products for livestock animals and humans and as a supplement in vitamins In water and sewer treatment plants calcium carbonate is employed in the removal of acidity and impurities Calcium Carbonate Uses The list of uses of calcium carbonate is given below

Calcium carbonate in both limestone and marble forms has also been used as a building material since ancient times Although limestone has a reputation for being relatively soft this hasn't stopped limestone buildings making a big impact For around 4000 years the Great Pyramid at Ghiza was the tallest building in the world - and it is constructed from 2 5 million

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
