“Precipitated calcium carbonate – different crystalline forms which yield to predetermined physical properties”

Special controls and a mastery of the parameters involved in the precipitation reaction and later treatments are required in order to produce precipitated calcium carbonates.

When comparing to standard ground calcium carbonates (GCC), precipitated calcium carbonates (PCC) can be distinguished for:

• the possibility to achieve smaller and more uniform particle sizes
• more stable and narrower granulometric distribution
• lower abrasivity
• higher specific surface
• highest chemical purity
• defined rheological properties
