FlockenGraphit

FlockenGraphit is a form of graphite characterized by flaky, plate-like microstructures. In industrial and academic contexts, the term refers to graphite flakes with a high aspect ratio, which contributes to anisotropic physical properties. FlockenGraphit is commonly associated with natural flake graphite but can also denote synthetically produced flakes that mimic the same morphology.

The flakes have large lateral dimensions relative to their thickness, typically tens to hundreds of micrometers across and submicrometer to a few micrometers thick. The layered carbon structure provides high electrical conductivity and thermal conductivity along the planes, while the interlayer sliding yields lubrication. The material is chemically inert under ambient conditions and exhibits low density.

Production methods for FlockenGraphit include mining and beneficiation of natural flake graphite, followed by crushing, milling, and classification to obtain flakes of the desired size. Synthetic routes include milling of polycrystalline graphite or chemical and physical exfoliation to generate platelets. Purification and surface treatment may be applied to improve compatibility with polymers or binders.

Applications span electronics and energy storage, where FlockenGraphit is used as a conductive additive in polymer composites and as an additive or minor component in lithium-ion battery anodes and electrode materials. It also serves in lubrication, friction materials, paints, and conductive coatings, where its conductivity and lubricity are advantageous.

Safety considerations emphasize dust control during processing to prevent respiratory exposure. Graphite itself is considered to pose low acute toxicity, but inhalable dust can pose health risks; appropriate industrial hygiene measures are recommended.
