Calcium carbonate appears as white, odorless powder or colorless crystals. Practically insoluble in water. Occurs extensive in rocks world-wide. Ground calcium carbonate (CAS: 1317-65-3) results directly from the mining of limestone. The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form. Precipitated calcium carbonate (CAS: 471-34-1) is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a by-product of the Solvay process (which is used to make sodium carbonate). Precipitated calcium carbonate is purer than ground calcium carbonate and has different (and tailorable) handling properties.
CAMEO Chemicals
Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis. (NCI04)
NCI Thesaurus (NCIt)
Calcium carbonate is a calcium salt with formula CCaO3. It has a role as an antacid, a food colouring, a food firming agent and a fertilizer. It is a calcium salt, a carbonate salt and a one-carbon compound.
The Macadamia Oil is cold pressed from the best quality of Macdamia nuts grown in South Africa. Macadamia Oil is very versatile in its use and is well known for its health benefits. It contains high amounts of Iron, Magnesium, Calcium, Calium, Vitamin A, B1,B2 and E.
Its wonderfully smooth buttery flavor makes Macadamia Oil perfect for roasting, baking. Due to the smoke point of 210 -234 degrees it can also be used for deep-frying.
