Calcium Carbonate (PCC)

Product Description

Chemically purified calcium carbonate with a content of calcium carbonate CaCO3

≥*8% Precipitated Calcium Carbonate (PCC) molecular weight***0.9 (by international atomic mass)

PCC Precipitated Calcium Carbonate is a highly dispersed white powder obtained by carbonation of calcareous milk with carbon dioxide. Chemical purity, absence of impurities, specified morphology and controlled particle distribution make this product a universal amorphous filler, which increases the efficiency of its use.

Scope of application:

1.1 Pharmacology-Medicines. It is included in the database of medicines that compensate for the lack of calcium and antacids.

1.2 Cosmetics industry - Functional filler, pigment. It is used for the production of toothpastes and powders, decorative cosmetics, face and hand skin care products.

Chemical characteristics of РСС:

• Whiteness is not less than *8.0%

• The mass fraction of calcium carbonate and magnesium carbonate in terms of

calcium carbonate not less than *8.5%

• The mass fraction of free alkali in terms of calcium oxide is not more than 0.*3%

• The mass fraction of substances insoluble in hydrochloric acid is not more than

0.1%

• The mass fraction of sand is not more than 0.**4%

• The mass fraction of one and a half oxides of iron and aluminum is not more than

Important features of MicroMarble

Carbonate calcium have certain features as such as:

• Increased strength of crushed grains
• Increased calcium content (more than *9,5%), in other words, there are few undesirable impurities coloring oxides of iron, titanium, manganese, cobalt, and therefore a small amount of water-soluble salts (less than **0 mg/l in Ca2+)
• Minimum porosity
• High indicator of witnesses
• Strong refraction
• Strong resistance to ultraviolet radiation
• Active dissolution in mineral acids.

In comparing with the others fillers (kaolins, silicates, silica) carbonate calcium is different for its high-level of whiteness.
