Experimental Verification for the Graphitization of Inertinite

چکیده
In order to explore the graphitization of inertinite, this paper conducted high-temperature thermal simulation experiments (HTT) and high-pressure (HTHP) on isolated samples enriched in inertinite. X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM) were used analyze process ① Results HTT: inertinite has a “threshold condition” with temperature threshold ranging between 2100 °C 2400 °C. Below threshold, d002 value remains above 0.342 nm. ② HTHP: (i) External forces have significant positive effect Compared HTT, addition external significantly reduces required for graphitization. (ii) Proper combinations pressure conditions are crucial efficiently promoting Changes pressure, either increasing or decreasing from optimal suppressive ③ The mechanism was analyzed. Shear stress promotes rotation orientation aromatic layers, while static hydrostatic contributes contraction reduction interlayer spacing carbon layers.
