Calcium threonate is a calcium salt of threnoic acid and a novel drug developed for the treatment of osteoporosis and as a calcium supplement. It is found in dietary supplements as a source of L-threonate used in the treatment of calcium deficiency and prevention of osteoporosis. The most common form is calcium L-threonate, or (2R,3S)-2,3,4-trihydroxy butyric acid calcium.

Dec 03, 2019· Calcium carbonate is used to prevent or to treat a calcium deficiency. There are many brands and forms of calcium carbonate available. Not all brands are listed on this leaflet. Calcium carbonate may also be used for purposes not listed in this medication guide.
Nov 01, 2014· In general, ultrafine ground calcium is obtained by the process of ultrafine wet grinding, and good dispersants should be added to obtain high quality ultrafine ground calcium carbonate. Small quantities of dispersants can remarkably improve the grinding efficiency, and have been widely used in ultrafine wet grinding processes.
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 .

Calcium Carbonate (CaCO 3) is one of the most widely used mineral fillers in the plastics industry, and its use in rigid packaging has increased significantly over the years. Once thought of simply as a resin extender, the addition of calcium carbonate in plastics has been shown to contribute to increased performance, improved processing, and improved sustainability of the finished part.
Sep 01, 2008· Furthermore, Dispersant-B and SN5040 are found to be the suitable dispersants for the dispersion of nanometer calcium carbonate. The grinding experiment of 325-mesh calcium carbonate reveals a linear relation between log tgrind and the weight percentage of fine particles, i.e. w .
type of dispersant has inappropriate chemistry to bond to calcium carbonate and is therefore ineffective on that type of filler (Figure 25.3). It has been said that fillers are either basic or acidic and furthermore that acidic dispersants should be used on basic fillers and that conversely, basic dispersants should beusedon acidic fillers.
