Natural flake graphite has a high degree of crystallinity, which equates to near theoretical true density, high thermal and electric conductivity, and low springback.
Commercial grades are available in purities ranging from 80-99.9% carbon, and sizes from 2 to 800 microns.
Applications for Graphite
Graphite is used in drilling fluids to provide lubrication, especially in complex drilling situations, to contribute to the control of fluid loss and to well-bore strengthening and to reduce torque and drag.
It can also be used in drilling fluids, potentially in conjunction with other minerals such as calcium carbonate or mica, as a loss-circulation prevention material where the natural flexibility of graphite ensures effective aperture sealing even when well-bore pressures vary.
