Additional information:
Carbon black is an engineered material, primarily composed of elemental carbon, obtained from the partial combustion or thermal decomposition of hydrocarbons. It exists as aggregates of aciniform morphology (i.e. shaped like a cluster of grapes) which are composed of spheroidal primary particles. While the fundamental building block of carbon black is the primary particle, these never exist in isolation, but are strongly fused by covalent bonds into aggregate. The primary particles are thus conceptual in nature since once the aggregate is formed the primary particles no longer exist as discrete entities and have no physical boundaries among them. Once produced, individual aggregates join together by van der Waals forces to form agglomerates. Agglomerates do not break down into smaller components unless adequate force is applied (for example, shear force). Primary particle and aggregate sizes are distributional properties and vary depending on the carbon black grade. Transmission electron micrographs demonstrate that while primary particle and aggregate sizes vary greatly within a given grade of carbon black, the primary particle size is essentially uniform within an individual aggregate.

Shape

Shape description
Shape category:
spheroidal
Shape:
other: The spheroidal category includes particles with aspect ratio up to 3:1 and thus this is a category for approximately “equilateral” particles. Examples of shapes included in this category are spherical, pyramidal, cubic, 3D star-shape.
