  • Introduction of natural graphite sheet

    The raw material of natural graphite film comes from natural graphite ore, which is totally different from synthetic graphite Its process is that natural graphite ore is crushed, screened, purified, floated, sintered and calendered, with a carbon content of 994~998% The thermal conductivity of natural graphite film ranges from 150 W/mK~500 W/mK, with 10~17g/cm3 density Because of itsThe surface of natural graphite ore can be oxidized during geological processes, as seen when comparing highpurity graphite, artificial GO, and natural graphite ore under microscopy studies A certain interfering region from the oxidized edge of graphite can be observed under orthogonal polarized light Compared to graphite oxide with a low oxidation degree produced in the laboratory, theStudy of oxidation process occurring in natural graphite
