This invention relates to calcium carbonate of different shapes including spindle, petal, whisker, needle, flake, ball and fiber. The calcium carbonate of such different shapes has an average particle size in the range of 10 mgr;m. This invention also relates to a process for preparing the said calcium carbonate with a controllable range of average particle size and .
The manufacturing process of precipitated calcium carbonate (PCC) is comprised of three steps. First, calcium oxide is obtained by calcination of limestone. The calcium oxide then turns into calcium hydroxide through a reaction with water (hydration process). Finally, PCC is manufactured by a reaction between the calcium hydroxide and carbonate ...
Apr 07, 2015· The present invention provides a process for preparing a precipitated calcium carbonate product. The process comprises the steps of preparing an aqueous suspension of precipitated calcium carbonate seeds by carbonating a suspension of Ca(OH) 2 in the presence of to moles of Sr, in the form of Sr(OH) 2, based upon moles of Ca(OH) .
According to the process, limestone is burned at a high temperature to form calcium oxide and, thereafter, calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered. The formation of the carbonate may be performed by carbonating calcium oxide with carbon dioxide gas in the presence of .
Precipitated Calcium Carbonate ... as well as the stability of the process. The whiteness and brightness of PCC are very critical, especially for office (white) paper manufacturing. Here, the impurities level must be well controlled, especially the iron oxide and manganese oxide.
