Sympatec Particle Size Analyzer for Calcium Carbonate
Determination of the pigment properties of calcium carbonate by particles size
The reality
Calcium carbonate is a commonly occurring mineral that is present in many rocks such as limestone and marble, as well as in the skeleton of stony corals, and is immensely versatile. In the construction industry, calcium carbonate is used as a raw material to produce lime cement and burnt lime or even as a solid block. In coal-fired power plants, it is used for flue gas desulphurisation and as a basic material for plaster production. Moreover, calcium carbonate is used as an additive in steel production, in fertiliser production and as a pigment in the paper and paint industries.
The required product characteristics, which are largely defined by their particle size distributions, are just as varying as the areas of application. A pigment obtains, for example, its maximum colour effect only in a narrow particle size range below 1 to 2 microns. However, the storage stability of pigment suspensions is also determined by the particle size. Whether produced mechanically by grinding or wet-chemically through precipitation, in each case the particle size distribution is a decisive quality criterion that should be continuously monitored where possible to ensure compliance. Here, the laser diffraction has a significant effect on quality assurance with its high-resolution measurement with analysis times of typically less than one minute.
