Recommended international nonproprietary name: Calcium carbonate [3]. Synonyms: E 170, calcite, aragonite, vaterite, chalk, CI pigment white 18 [4], drop chalk, prepared chalk, whiting, English white, Paris white [5].
What does precipitated calcium carbonate mean?
Precipitated calcium carbonate (PCC) is an innovative product derived from lime, which has many industrial applications. PCC is made by hydrating high-calcium quicklime and then reacting the resulting slurry, or “milk-of-lime”, with carbon dioxide.
What is precipitated calcium carbonate used for?
Precipitated Calcium Carbonate is used in several different areas of production such as the flooring, paint, and paper industry due to its mechanical and optical properties. Calcium carbonate is used in the paper industry both as a PCC filler and as a coating which allows for the paper to have such a pure white color.
What is precipitated calcite?
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.
What is precipitated chalk?
Precipitated chalk (also known as calcium carbonate or acid reducing powder) is used to reduce acidity (raise the pH) in wines (or other brews eg beer) that are too acidic.
What is another name for calcium?
The name for the element was taken from the Latin word for lime, calx. Calcite is the most common form of natural calcium carbonate (CaCO3).
What is a precipitated?
1 : to cause to happen suddenly or unexpectedly The misunderstanding precipitated a quarrel. 2 : to change from a vapor to a liquid or solid and fall as rain or snow. 3 : to separate from a solution The procedure called for precipitating salt from seawater.
What is the difference between calcium carbonate and precipitated calcium carbonate?
PCC differs from ground calcium carbonate (GCC) and kaolin clay in a very basic way. PCC is manufactured, while GCC and clay are mined from large natural deposits of ore. This fundamental difference gives rise to a number of advantages for precipitated calcium carbonate.
What does precipitated chalk mean?
Precipitated Chalk (calcium carbonate powder) is an acid reducer used to reduce the acidity in wines. It is also used when brewing cider or beers, especially the dark malty variety. Country wine that uses high acid fruit such as rhubarb or apple will need pure calcium carbonate due to the high acidity of these fruits.
How do you precipitate calcite?
decreasing the pressure of CO2 gas in the system causes calcite to precipitate from solution; increasing the water temperature decreases the amount of CO2 dissolved in water and causes calcite to precipitate; decreasing the water temperature increases the amount of CO2 dissolved in water and causes calcite to dissolve.
What is the scientific name for calcium?
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium.
