Carbon black The prime particle size of a carbon black grade determines to a large extent its degree of blackness - known as jetness - in dispersed form. This can be attributed to the effect of surface area: the finer the prime particle, the more surface area in the primary aggregate. Thus, finer prime particles give jetter colour due to the increased surface area available for light absorption. Another property of carbon black is its ability to provide undertone ranging from blue to brown. A blue undertone contributes to the appearance of jetness. A key property of carbon black that controls its performance is the structure of the primary aggregate. A carbon black characterized by primary aggregates composed of many prime particles with considerable branching and chaining is referred to as a high-structure carbon black. On the other hand, if the primary aggregate consists of relatively few prime particles making up a more compact unit, the carbon black is referred to as a lowstructure carbon black. Structure influences the ease with which the carbon black is dispersed into a resin, ink base, or other material. All carbon blacks have oxygen 9
