Carbonation is one of the methods for the production of precipitated calcium carbonate (PCC) on the industrial scale. A gaseous CO2 is used as a reagent in this process.
Rhodolith beds are major biogenic calcium carbonate producers, with production rates that can be similar to those of coral reefs. Production rates vary latitudinally because of differences in abiotic and biotic drivers, but the different methods used to estimate CaCO 3 production rate may also explain some of the wide variation among estimates. We used a 378 …

long-term physical or chemical effects of Calcium Carbonate as part of a HDPE conduit formulation. Therefore, for reasons of long-term product safety and reliability, PPI recommends against the use of Calcium Carbonate (CaCO 3) additives in HDPE conduit formulations, with the exception of additives used in the color concentrate formulations.
Marine biogenic calcium carbonate (CaCO 3) cycles play a key role in ecosystems and in regulating the ocean's ability to absorb atmospheric carbon dioxide (CO 2).However, the drivers and magnitude of CaCO 3 cycling are not well understood, especially for the upper ocean. Here, we provide global-scale evidence that heterotrophic respiration in settling marine …
The impact specification is usually more difficult to meet in a small diameter pipe, thus a finer calcium carbonate must be used—usually in the range of 1-2 microns. In applications that require ...
