This flake graphite product (800 mesh) is a purified natural graphite developed for experimental and research applications in advanced carbon materials. Characterized by its layered crystalline structure and high purity, it serves as a key precursor for synthesizing graphene, expanded graphite, and graphite-based lubricants. While derived from natural graphite, it requires further processing—such as coating or composite formation—before use as a lithium-ion battery anode material. The 800-mesh particle size offers a fine, consistent powder suitable for controlled dispersion and compounding in laboratory-scale preparations. With available quantities ranging from 20 g to 1 kg, this material supports diverse studies in low-dimensional carbon systems and three-dimensional graphite architectures. It is particularly relevant for researchers investigating graphite exfoliation, conductive additive formulation, or thermal management materials.
