Calcium carbonate is the most widely used filler in terms of the number of applications in polymer. The cheapest grades are low in price and are used primarily to reduce costs. By contrast, the finest grades are an order of magnitude higher in price and are used to modify various properties, both during processing and in the final compounds 13. Some studies have

The pH at equilibrium is higher for water with lower calcium content, i.e. for softer water. In December 2012, a new German standard for the calcu-lation of calcium carbonate saturation in drinking water was

16.11.2007  In the last few years, evidence has accumulated that calcifying organisms are likely to be affected by ocean acidification. Therefore, the production of calcium carbonate will probably decline, although conversely global warming, increasing stratification and sea level rise may also stimulate increases in global calcification. As acidification reaches the deep ocean, it
