The invention relates to a process for regulating the porosity and properties of paper, in particular uncoated wood-containing paper such as SC-paper, wherein a sufficient quantity of colloidal PCC having a BET surface area of 10-100 m2/g is used as a filler in the paper to achieve a desired porosity of the paper; as well as paper containing colloidal PCC as filler, and a pigment ...
4.2. Carbonated Apatite in Physiological Solutions The studies on slow spontaneous precipitation of calcium carbonates and calcium phosphates under physiological conditions [218], show that calcium carbonate precipitation is prevented by the presence of phosphate ions at concentrations too low for the precipitation of calcium phosphate.
Precipitated calcium carbonate (PCC) is a versatile material that can be used in many industries such as paper making, pharmaceutical, cosmetic, paint, plastic, sealant, toothpaste, and food mainly as a filler product, Table 3, [1, 7].

Full Article. Pre-flocculation of precipitated calcium carbonate filler by cationic starch for highly filled mechanical grade paper. Yizhou Sang, a Michael McQuaid, b and Peter Englezos a, * Three commercial starches were evaluated in conjunction with colloidal silica and flocculant to retain precipitated calcium carbonate (PCC) filler.
Calcium carbonate can also be produced synthetically in the form of Precipitated Calcium Carbonate (PCC). The transformation process consists in decarbonating limestone to separate CaO and CO 2, and then recombining these elements in a chemical reactor.The final product has the same chemical composition as GCC, but with different properties in terms of particle size distribution, particle ...

Applications of Precipitated Calcium Carbonate (PCC):. Paper Industry: Precipitated Calcium Carbonate is a widely used product in paper industry. It is well established as a filler and coating pigment for producing paper products of premium quality. It is produced in the form of slurry at precipitated calcium carbonate plants which are situated near paper mills.
Precipitated calcium carbonate (PCC) is synthetic calcium carbonate that has high purity of more than 98 wt% of CaCO3 content. Owing to its unique characteristic whereby its shape and size can be ...
In this paper are reported experimental results on the effect of a magnetic field on the precipitation process of calcium carbonate scale from a hard water. Carbonically pure water was circulated at a constant flow rate in a magnetic field. After this treatment, calcium carbonate precipitation was induced by degassing dissolved carbonic gas.
