Producing a New Expanded Graphite by Re-Intercalation of Expandable Graphite
Applied Mechanics and Materials, 2014A new expanded graphite was prepared by re-intercalation and expansion of expandable graphite. The products were characterized by scanning electron microscope. Compared with the common expanded graphite, the network pores of this expanded graphite are more developed.

Graphite foam from pitch and expandable graphite
Carbon, 2014Graphite foams were prepared from a coal tar pitch that was partially converted into mesophase. Expandable graphite was used instead of an inert gas to "foam" the pitch. The resulting foam was subjected to a series of heat treatments with the objective of first crosslinking the pitch, and thereafter carbonizing and graphitizing the resulting foam.

Densification of expanded graphite
Carbon, 2002A brief theoretical investigation of the behavior of exfoliated graphite (EG) undergoing compaction is presented. Simple arguments and assumptions allow one to calculate the density of the initial individual worm-like particles of EG for any final porosity of the resultant consolidated blocks. These results as well as excluded volume considerations are

Performance of expanded graphite and expanded milled‐graphite fillers in thermosetting resins
Polymer Composites, 2005AbstractEpoxy/expanded graphite (EG) and polyester/EG composites were prepared with the aid of sonication, while epoxy/expanded‐milled graphite (epoxy/milled‐EG) and polyester/expanded‐milled graphite (polyester/milled‐EG) composites were prepared on a three‐roll paint mill.

Absorption Process of Expanded Graphite
2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010Different expansion volume of expanded graphite was used for oil absorption experiments. The structure of expanded graphite was studied by scanning electron microscope (SEM) and optical microscope before oil-absorption and after oil-absorption. It was found that viscosity, expansion volume and particle size are the three key factors for the higher ...

On lower-nitrogen expandable graphite
Materials Research Bulletin, 2000Abstract The intercalation reaction of a mixture of HNO 3 and acetic anhydride to form expandable graphite was investigated. Expandable graphites were prepared from the intercalation compounds (GICs) by rapid heating up to 900°C. The effects of reaction conditions on the quality of the expandable graphites were studied and the optimum conditions for
