Description

The various production processes for obtaining Carbon Black have their advantages and each process is characterized by a certain product range. The key parameters, as shown in Table 1, provide an overview of the characteristic data for the main Carbon Black production processes. 

Each process shows a characteristic primary particle diameter distribution curve. An electron microscope image of the individual Carbon Black type is used to determine the quantity and size of the primary particles, which then yields the number of specific diameter clusters.

Table 1 - Carbon Black variance for different production processes.

Fig. 1 shows the primary particle size distribution curve for each of the main production methods. Fine Carbon Blacks (Gas Blacks) for instance are clustered in a relatively narrow primary particle size range. Coarser Carbon Blacks exhibit flatter curves.
