why calcium carbonate caco3 is metallic in algeria

Is CaCO3 the answer to your appliions'' requirements?

Calcium carbonate is basically a fine white powder; once the calcium is dispersed into a plastic system, it will add haze (which explains why it is commonly used as a TiO 2 extender). While displacement of TiO 2 masterbatch with CaCO 3 concentrate offers another cost saving opportunity, CaCO 3 alone is not going to drastically increase the opacity of the product like a TiO 2 colorant.

Water Research Center - Alkalinity and Stream Water …

If CaCO3 actually accounts for most of the alkalinity, hardness in CaCO3 is equal to alkalinity. Since hard water contains metal carbonates (mostly CaCO3) it is high in alkalinity. Conversely, unless carbonate is associated with sodium or potassium which don''t contribute to hardness, soft water usually has low alkalinity and little buffering capacity.
