Naturally occurring sedimentary rock. Limestone (Ground): CAS-No. 1317-65-3 Ground with non-hazards auxiliary agents Silica, quartz (CAS No 14808-60-7) naturally-occurring impurity of calcium carbonate in trace amounts. Magnesium Carbonate (CAS No 13717-00-5) is also naturally present in Limestone.
Mar 09, 1999· In particular, paper coating compositions used in high-speed coating machines are usually prepared from a slurry of 70 to 80% solid concentration of wet-ground calcium carbonate of the #95 and #90 grades for top coating and wet-ground calcium carbonate of #75 and #60 grades for under-coating.
In addition to kaolin and talc, calcium carbonate is used in the paper industry as a filler and coating pigment in the production of paper. Since calcium carbonate is rhombohedral even when very finely ground, it is primarily used in papers with the highest degree of whiteness and good printability.
Every time. That’s HuberCal pure and natural calcium carbonate. HuberCal gives you a higher calcium carbonate assay – typically greater than 99%. This degree of purity is why food companies, calcium salts producers and pharmaceutical and dietary supplement manufacturers have come to rely on HuberCal pure and natural calcium carbonate.
