Calcium Carbonate Nanoparticles

• Catalog Number: ACM471341-1
• Chemical Name: Calcium Carbonate Nanoparticles
• CAS: 471-34-1
• Category: Nanopowder Compounds
• Description: 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.;Limestone is an odorless, white to tan powder.;Limestone (calcium carbonate) that has been recrystallized by metamorphism and is capable of taking a polish.
