Amorphization of graphite induced by mechanical milling

Amorphization of graphite as a result of prolonged high-energy ball milling was directly observed with HREM. The exothermic peak in the DTA trace of the ∼200 h ball-milled sample indicated a crystallization onset temperature of about 670 °C and crystallization activation energy of 234 kJ/mole.

Carbon fibers - Wikipedia

Carbon fibers or carbon fibres are fibers about 5–10 micrometres in diameter and composed These properties have made carbon fiber very popular in aerospace, civil engineering, military, and motorsports, along with Many examples of this type of application can be seen in DIY heated articles of clothing and blankets.

About Graphite - Graphite Products - Superior Graphite

The earliest use of graphite dates back to primitive man, who used it to draw on cave walls. to line molds for the purpose of making smoother cannon balls, which could be fired farther. The family of graphite materials includes amorphous graphite, crystalline flake and vein Purified/Heat Treated Graphites & Carbons.

Ceramic - Wikipedia

A ceramic is a solid material comprising an inorganic compound of metal or metalloid and Many composites, such as fiberglass and carbon fiber, while containing decreasing porosity through the use of glassy, amorphous ceramic coatings on top If later heat treatments cause this glass to become partly crystalline, the

Structural disorder and phase transformation in graphite

In the present experiment, when the nanocrystalline graphite, with which some amorphous graphite may coexist, after 16 h of milling is heated to 1300, the crystallite sizes of heat-treated graphite are calculated to be 1.8 and 2.0 nm, respectively, from the XRD pattern shown in Figure l(f) and the Raman spectrum shown in Figure 2(f).
