 1. The blackness and particle size
Blackness directly associated with the particle size of pigment carbon black, the smaller the particle size, the higher the blackness of the black pigment. This is because even though the primary particles fuse into a native has condensed matter, but its specific surface area has its role, primary particles is fine, the greater the surface area of the condensed matter. Color more black, presented by the uv effect is better. Because of the fine particle black carbon absorption rate is higher than coarse carbon black particles, so the tinting strength is stronger. But when the particle size reduced, because the blue light is absorbed by the optimal first, for this color become brown.
2.Structure 
Carbon black particles not only in the form of primary particles, and in the production process often fused into condensed matter. That is a primary particles agglomeration by chemical bonds. In condensed matter, composed of a chain of native agglomerations composed of carbon black is called high structure carbon black. And native agglomerations composed of primary particles less chain branches carbon black and density is bigger, it is called a structure of low carbon black.
