Chalk. Used in papermaking as a filler or coating pigment
Known commonly as "chalk." Calcium carbonate is used to precipitate acids in high-acid wines. However, due to its tendency to leave chalky residues or promote oxidation during treatment, better steps to reduce acidity are recommended; dilution, blending, and malo-lactic fermentation being the most important.

A salt, CACO3; under certain conditions, will precipitate out of the water of the Great Salt Lake, forming aragonite or calcite
Calcium is found in nearly all natural water supplies. Calcium oxide, known as quicklime, combines with water to form calcium hydroxide, or hydrate, known also as caustic lime or slaked lime, and soluble in water to form lime water. If there is an excess of the hydrate, the mixture is known as milk of lime, or white-wash. Calcium oxide combines with carbon dioxide to form calcium monocarbonate, which occurs in nature as calcite, marble or limestone. This substance by itself is only' slightly soluble in pure water, but with the addition of another molecule of carbon dioxide and one molecule of water, it forms calcium bicarbonate, which is highly soluble, and is the form in which calcium is taken up from calcium carbonate rocks by rain water, which contains carbon dioxide in solution.

A mined material (chalk) that is used as an extender or filler for paint and sealant.
the chemical name for limestone. Its formula is CaCO. All carbonates are insoluble in water. Calcium carbonate is one of the minerals responsible for hard water.
The main component in chalk, food grade calcium carbonate can be used to decrease acid (primarily tartaric acid) in wines. Due to the undesirable flavor calcium carbonate imparts to wine in large amounts, it typically should not be used to decrease acidity by more than four tenths of a percent (4g/ml). Many winemakers prefer blending a high acid wine with a lower acid wine to decrease acidity rather than resort to the addition of chalk. Campden Tablets Consisting of either Potassium Metabisulfite or Sodium Metabisulfite, Campden tablets are a convenient way to accurately measure sulfite additions to wine. The tablets should, however, be crushed before they are added making them often less convenient than sulfites in powdered form.
Chemical that also occurs in limestone and marble.
Crystal compound that is formed and sticks to spa/pool walls and equipment in the form of scale, when calcium, pH and total alkalinity levels are too high.
A capsule and tablet diluent, used to evenly disperse ingredients to provide improved consistency.
Chemical compound (CaCO3) in limestone and marble. Common component of sea water and may precipitate on the bottom of a sea, lake, etc.
CaCO3 is a naturally occurring substance found in a variety of sources, including chalk, limestone, marble, oyster shells, and Tums. Used as a filler in the alkaline paper manufacturing process, calcium carbonate improves several important paper characteristics, like smoothness, brightness, opacity, and affinity for ink; it also reduces paper acidity.
a white pigment that is used in the furnish or coating process of the paper.
Calcium carbonate is a chemical compound, with chemical formula CaCO3. It is commonly used medicinally as a calcium supplement or as an antacid. Calcium carbonate is the active ingredient in agricultural lime. It is a common substance found as rock in all parts of the world and is the main component of seashells and the shell of snails. It is usually the principle cause of hard water. (courtesy of wikipedia.org)
CaCO3. The chemical term for Chalk and limestone.
Calcium Carbonate (CaCO3) is a common oilfield scale formed either by the mixing of incompatible waters or due to temperature, pH and pressure changes that reduce the solubility of these ions in solution. Areas of concern for deposition in a production system may be chokes, heat exchangers and downstream from where fluids from different wells mix. A white solid that can be remediated using acid treatments.

It occurs in oyster shells, chalk, limestone, marble and travertine, and is a major cause of boiler scale when hard water is used in heating systems. It can be mined from natural surface deposits or precipitated (made synthetically) by reaction of calcium chloride and sodium carbonate in water solution, or by passing carbon dioxide through a suspension of hydrated lime (Ca(OH)2) in water. It is soluble in acids with evolution of carbon dioxide. [2
