Ternary Intercalation Compound of Graphite with Aluminum Fluoride and Fluorine
نویسندگان
چکیده
A ternary intercalation compound of graphite with AIF3 and F2, CXF(A1F3)J/ was prepared under fluorine atmosphere at temperatures of 20-400 °C. The typical 1st stage compound has a composition of C6F(AlF3)o,i5 with a repeat distance of 940 pm. Rapid progress in the reaction led of the formation of graphite fluoride, (C2F),,. ESCA spectra indicate that the chemical bond between host graphite and intercalated fluorine has nearly covalent nature similar to that for (C2F)n.

The Effect of Raw Material Ratios on the Fe-TiC/Al2O3 Composite Formation Mechanism
Ilmenite, aluminum and graphite can be used to produce in-situ Al2O3/TiC–Fe composites which are used as cutting tools. Few publications can be found in the literature that discusse the effect of molar ratio of aluminum and graphite on the Al2O3/TiC–Fe formation mechanism. Therefore, the present research is designed to make the issue clear. To achieve this goal, at first, the mechanism o...

Interactions between fluorine (as F) and aluminum (as Al) have recently attracted much attention following reports of their possible involvement in Alzheimer’s disease (AD). An inverse correlation has been demonstrated between the incidence and severity of AD and the level of fluorine in drinking water.1-4 Aluminum has long since been implicated in the etiopathology of AD, and neurotoxicity stu...
متن کاملPreparation and characterization of a tetrabutylammonium graphite intercalation compound.
The intercalation of tetrabutylammonium (TBA) cations into graphite by cation exchange from a sodium-ethylenediamine graphite intercalation compound yields a single-phase first-stage product, C(44)TBA, with a gallery expansion of 0.47 nm. The gallery dimension requires an anisotropic "flattened" cation conformation.
متن کاملFluorine in medicine
Fluoride has long been known to influence the activity of various enzymes in vitro. Latterly it has been demonstrated that many effects primarily attributed to fluoride are caused by a synergistic action of fluoride plus aluminum. Fluorinated chemicals are of growing importance, with applications in medicine. Fluorine substitution has profound effects on the properties of organic compounds. The...
