This complete color change indicated the oxidation of graphite to graphite oxide (GTO) at higher level. The model in Scheme 1(f) shows that the GTO suspension with acids and metal ions is directly filtered, and then the surface of the filter is quickly covered with a compact film, which could block the water passing (Scheme 1(g) ).

Graphene, graphene oxide chemistry aplications

Graphene Oxide, the monomolecular sheets of graphite oxide is a compound of carbon, oxygen, and hydrogen in variable ratios, obtained by treating graphite with strong oxidizers. Graphene oxide sheets have been used to prepare a strong paper-like material, and have recently attracted substantial interest as a possible intermediate for the manufacture of graphene.

The Effect of Temperature Cycling on Magnetic

We report the structure and magnetic studies of carbon coated nanoparticles of Ni and Co synthesized in a special low carbon: metal ratio arc chamber. Powder x-ray diffraction (XRD) profiles and lattice plane spacing measurements from high resolution TEM indicate particles of FCC Ni or Co and graphitic coating with no evidence of carbides or solid solutions of carbon in the metal.

Graphite machining

2019/7/15The graphite material is a giant block, plate, or bar when it is shipped from the factory. When manufacturing the electrode, the cutting process must be carried out. The cutting can use the high efficiency band saw, the saw blade is made of 10mm wide, carbon steel with 2.5mm pitch, the saw blade line speed can reach 900m/min.

Effect of Oxygen Content on Structures of Graphite Oxides

Graphite oxide was synthesized by the oxidation of graphite via a modified Hummers approach. The oxygen content of graphite oxide was tuned by changing the oxidation time. The saturated ratio of oxygen to carbon is 0.47. Furthermore, the effect of oxygen content on the structures of graphite oxide was evaluated by using SEM, TEM, XRD, Raman, FTIR, TG, TPD-MS, and nitrogen adsorption. It was

Graphite crucible's production process

2016/1/30Graphite crucibles should be protected against moisture. The graphite crucible is most afraid of moisture, and it has a great influence on the quality after being exposed to moisture. If a damp crucible is used, cracks, explosions, fall-offs and bottom-outs will occur, resulting in the loss of molten metal and even industrial accidents.
