A new solid lubricant [PDF]

, 1969
Friction and wear life studies on burnished films of the compound graphite fluoride have demonstrated its potential as a solid lubricant material. It is effective in moist air, dry air, or in dry argon at temperatures up to approximately 400 degrees ...

Deep treatment of low-concentration fluorine wastewater based on the graphite bipolar-driven electrocoagulation method

Desalination and Water Treatment
Graphite bipolar-driven aluminum plate electrocoagulation was used to deep-treat wastewater with low concentrations of fluorine. Looked into how the removal effect was affected by current density, electrolyte type, and electrolyte concentration.

Electrochemical synthesis of carbon-metal fluoride nanocomposites as cathode materials for lithium batteries

Electrochemistry Communications, 2020
Herein we have demonstrated an electrochemical method for the synthesis of carbon-metal fluoride nanocomposites (CMFNCs). Electrochemical intercalation of transition metal ions into graphite fluoride (CFx) resulted in the formation of CMFNCs.

Reaction of graphite fluoride with NaOH–KOH eutectic

Journal of Fluorine Chemistry, 2008
Abstract Graphite fluoride has been generally considered chemically inert against strong alkalis under ambient conditions. In the present study we demonstrate that treatment of graphite fluoride with eutectic NaOH–KOH mixture at 250 °C induces dramatic structural and textural changes in the solid as evidenced by XRD, FT-IR, Raman, UV–vis absorption ...

Anodic dissolution of metals in oxide-free cryolite melts [PDF]

, 2005
The anodic behavior of metals in molten cryolite-alumina melts has been investigated mostly for use as inert anodes for the Hall-Héroult process. In the present work, gold, platinum, palladium, copper, tungsten, nickel, cobalt and iron metal electrodes ...

Highly Stable Fluorine-Intercalated Graphite Fibers Coated with Graphite Fluoride Film

TANSO, 1993
The stability of fluorine-intercalated graphite fibers were improved by the surface coating of the fibers with graphite fluoride film. The preparation process of the GIC was composed of two steps. In the first step, the pitch-based graphite fibers were pre-treated with elemental fluorine at the temperature range of 300-410°C, so that the surface of the
