Characteristics and applications of graphite fluoride

Physica B+C, 1981
Abstract Two kinds of graphite fluorides, (CF) n and (C 2 F) n , are prepared by the reaction of elemental fluorine with carbon materials at temperatures of 350–640°C. (CF) n has a chair-type structure different from that of (C 2 F) n , which is a so-called second stage compound having C-C bond perpendicular to the carbon network. The heats

GRAPHITE FLUORIDE AS A SOLID LUBRICANT

Industrial Lubrication and Tribology, 1973
SOLID lubricants such as molybdenum disulphide and graphite have been incorporated in bonded lubricating films for some years, but work is constantly proceeding to develop improved products that provide reduced friction, less wear, are easier to use, or have other valuable features. One of the more recent additions to this type of lubricant is graphite

The Preparation and Tribological Properties of Graphite Fluoride

Advanced Materials Research, 2014
Solid phase method was adopted to prepare the graphite fluoride solid lubricant. The friction and wear properties of graphite fluoride were tested with MMW-1 vertical universal friction and wear testing machine. The phase of graphite fluoride was analyzed with infrared spectrometer.

The surface and structural properties of graphite fluoride

Carbon, 2015
Abstract The structural properties of graphite fluoride are not well characterized despite many experimental and theoretical studies. Computational investigations have indicated the existence of several possible stacking sequences for this material, but the methods used were incapable of adequately describing the dispersive interactions between ...

Interaction between Nuclear Graphite and Molten Fluoride Salts: A Synchrotron Radiation Study of the Substitution of Graphitic Hydrogen by Fluoride Ion

The Journal of Physical Chemistry A, 2012
The interaction between nuclear graphite and molten fluoride salts (46.5 mol % LiF/11.5 mol % NaF/42 mol % KF) is investigated by synchrotron X-ray diffraction and C K-edge X-ray absorption near-edge structure (XANES). It is found that there are a large number of H atoms in IG-110 nuclear graphite, which is attributed to the residual C-H bond after the

Lamellar Compounds of Graphite with Chromyl Chloride and Chromyl Fluoride

Nature, 1951
THE ability of graphite to form lamellar compounds by occluding certain other substances (fluorine, boron, oxygen, potassium, rubidium, caesium and ferric chloride) between its layer planes has been known for a considerable time. No new compounds of this type have, however, been reported for the past fifteen years, though attempts have been made to ...

ESR study of graphite-fluorine and graphite-fluoride acceptor intercalation compounds

Synthetic Metals, 1983
Abstract We report an in situ ESR study of the graphite-fluorine system as well as of the graphite-fluoride acceptor intercalation compounds C:PF5:F2, C:GeF4:F2, C:AsF5, C:SbF5, C:IF5:F2, etc., with emphasis on the ESR line-shape (A/B ratio) and linewidth.
