Ball Milling - an overview | ScienceDirect Topics

Ball milling of graphite with appropriate stabilizers is another mode of exfoliation in liquid phase. 21 Graphite is ground under high sheer rates with millimeter-sized metal balls causing exfoliation to graphene (Fig. 2.5), under wet or dry conditions.For instance, this method can be employed to produce nearly 50 g of graphene in the absence of any oxidant. 22 Graphite (50 g) was ground in ...

Nanoparticle - Wikipedia

A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, [citation needed] or fibers and tubes that are less than 100 nm in only two directions. At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.
