كربونات الكالسيوم: استخدامات ومحاذير
Biological sources [ ] Calcium carbonate chunks from , shells and most are predominantly calcium carbonate and can be used as industrial sources of that chemical
When a glaze containing this material is fired in a kiln, the whiting acts as a material in the glaze Calcium carbonate is also used in applications eliminating harmful SO 2 and NO 2 emissions from coal and other fossil fuels burnt in large fossil fuel power stations
cables can use calcium carbonate at loadings of up to 70 phr parts per hundred parts of resin to improve mechanical properties tensile strength and elongation and electrical properties volume resistivity Cold-water carbonates do exist at higher latitudes but have a very slow growth rate
