Graphite oxide powder with its small thermal expansion, and thermal conductivity, thermal shock resistance and chemical stability, and many other advantages and to fit for the steel smelting harsh environment refractory raw material, but graphite in the water and wettability, dispersion sent in air shortcomings, such as easy oxidation limits its further applications. This papers to the inorganic salt (nitric acid aluminum, oxygen chlorinated zirconium, three chlorinated titanium) as raw material, the rare in graphite nanocolloidal suspension of non-uniform application into nuclear technology, make hydrolysis product (hydration oxide deposits to micron grade flake graphite surfaces, the washing and drying and heat treatment, the graphite/oxide compound preparation powder. This paper mainly of composite powder preparation process condition and performance. Through the coated rate, oxidation weightlessness rate, morphology observation, grain size and specific surface area and analysis found that, non-uniform nucleation process of pH value, coating solution temperature, the cladding precursors concentration on the several factors of graphite surface coating layer have important influence on the form.
Dispersion behavior of graphene oxide in different organic solvent impact . As-prepared graphite oxide may be dispersed , N-dimethylformamide, N-methyl-2-pyrrolidone, tetrahydrofuran , ethylene glycol . In all of these solvents , all of the stratum corneum is divided into individual graphite oxide materials , single-layer graphene oxide film group , was achieved. Exhibited dispersed graphene oxide sheets between the long-term stability and a few hundred nanometers and several microns large , a similar situation dispersed graphene oxide in water . These results should be easy to handle and deal with the graphene-based materials used in different environments .
