CONCLUSIONS Ferric chloride intercalates graphite fluoride easily, resulting in a product containing iron halide crystals and first-stage FeCl3 intercalated GIC.
This process enables intercalation with FeQ3 to take place with carbon materials that have a very low degree of graph- Cited by: 9. The reaction between graphite fluoride and ferric chloride was observed in the temperature range of to °C.
The graphite fluorides used for this reaction have an sp 3 electronic structure and are electrical by: 9. ABSTRACT-The reaction between graphite fluoride and ferric chloride was observed in the temperature range of to 'c. The graphite fluorides used for this reaction have an Sp3 elec-tronic structure and are electrical insulators.
They can be made by fluorinating either carbon fibers or powder having various degrees of graphitization. We use anhydrous ferric chloride (FeCl3) to intercalate graphite flakes consisting of 2−4 graphene layers and to dope graphene monolayers. The intercalant, staging, stability, and doping of the resulting intercalation compounds (ICs) are characterized by Raman scattering.

Fluorine-graphite intercalation compound (GIC) has been prepared from pitch-based carbon fiber and powdery natural graphite in the presence of silver fluoride.
Prepared compounds. A ternary intercalation compound of graphite with AIF3 and F2, CXF(A1F3)J/ was prepared under fluorine atmosphere a t temperatures of °C. The typical 1st stage compound has a composition of C6F(AlF3)o,i5 with a repeat distance of pm.
Rapid progress in the reaction led of the formation of graphite fluoride, (C2F). ESCA spectra. Intercalation Compound Graphite Crystal Alkali Metal Atom Graphite Intercalation Compound Intercalate Layer These keywords were added by machine and not by the authors.
This process is experimental and the keywords may be Cited by: 9. All the features of fluorine-graphite intercalation compounds, C x Fs have been reviewed by citing from the first publication on these compounds to thenewest one.
C x Fs are synthesized by several different methods in the presence of various kinds of fluorides. The products and their properties strongly depend on the reaction rates. Fluorine intercalation in anhydrous liquid HF Author: Tsuyoshi Nakajima.
Graphite-copper (II)-chloride intercalation compounds can be obtained by heating for eight days a mixture of graphite and anhydrou copper (lI)-chloride in a chlorine atmosphere to a temperature of C.
Thus, up to a maximum amount of Wt.-percent can be incorporated in the mixture of copper (II) by: 9. A doubly-filled graphite-ferric chloride-dinitrogen pentoxide intercalation complex of empirical formula C 31 FeCl 3 (N 2O 5) has been prepared in which a fourth stage graphite–ferric chloride complex is independently interleaved by a second stage graphite–dinitrogen pentoxide complex.

Ferrix Chloride-Graphite Intercalation Compounds Prepared From Graphite Flouride. By Ching-Cheh Hung. Abstract. The reaction between graphite fluoride and ferric chloride was observed in the temperature range of to C.
The graphite fluorides used for this reaction have an sp(sup 3) electronic structure and are electrical insulators. Author: Ching-Cheh Hung. Another drawback of the intercalation and exfoliation process is that the above process cannot be used to control the amount of exfoliation or to produce nano-particle sized graphite flakes.
Consequently, the expanded graphite flake produced from the process will have a thickness of at least 10 microns or greater, Cited by: Graphite intercalation compounds Graphite consists of hexagonal carbon planes stacked along c-axis by weak van der Waals force.
Therefore, many substances, what is called intercalates, can enter into the gallery of the graphite to form graphite intercalation compounds (GICs).
The GICs have a unique stage structure. Get this from a library. Ferric chloride graphite intercalation compounds prepared from graphite fluoride. [Ching-cheh Hung; United States. The properties of graphite intercalation compounds (GIC's) are discussed with respect to possible applications.
Five families of intercalates give high electrical conductivity to GIC's: pentafluorides leading to high conductivity, 10 8 S/m (higher than metallic copper); metal chlorides; fluorine and alkali metals with bismuth giving relatively high conductivity of the order Cited by: Ferric Chloride Graphite Intercalation Compounds Prepared from Graphite Fluoride June The Frequency Dependence of the Resistivity of Pristine and Intercalated Graphite Fibers from DC to 10 MHz Kinetic Studies of the Bromine Intercalation of Pitch-based Fibers Intercalation Compounds of Graphite.
