The Properties of Graphite

After a brief period of use, the graphite tubes and rods that are commonly employed In electrothermal atomizers begin to deteriorate, and their electrical characteristics become subject to drift (7,9,47). This is one of the most troublesome sources of analytical variability. Maessen et al (47) demonstrated that the properties of graphite (e.g. porosity ancl conductivity)... [Pg.251]

The properties of graphite are strongly anisotropic, the electrical conductivity varying with direction by a factor of in ... [Pg.503]

The most stable graphites are the near-isotropic materials ". The effects of irradiation on the properties of graphite are governed by neutron energy, neutron fluence, temperature, temperature gradients, and structure and type of graphite used. The effects of irradiation are dimensional changes, reduction in thermal conductivity, and enhancement of creep rates. [Pg.598]

Fullerenes Ceo and C70 (more than 99% purity) were deposited on Chromosorb 750 (England) from the saturated solutions in o-dichlorobenzene. Carbopack C HT the adsorption properties of which is similar to the properties of graphitized carbon black was... [Pg.905]

Diamond is the hardest known substance, and apart from its commercial value as a gemstone, it has apphcations in cutting tools and abrasives (see Box 13.5). The structural differences between diamond and graphite lead to remarkable differences in physical properties (see Section 13.3) and uses. The properties of graphite that are exploited... [Pg.339]

The Wigner Disease . Wigner had contributed to the quantum mechanics of solids with his calculations, together with Seitz, of the cohesive energy of crystals. It was therefore natural for him, especially with his background in chemistry, to worry about the effect of neutron bombardment on the properties of graphite. He, together with F. L. Friedman and F. Seitz, estimated the number of displacements that a moderator atom would suffer in the course of... [Pg.16]

Modification of the properties of graphite paste by incorporating ionic charge sites also has been investigated (Lane, unpublished) and may be useful in the near future. At present it can be said that all of the electrodes modified for greater in vivo selectivity are exploratory in nature and results with them must be interpreted with caution. While progress in this direction can be assured, there should be no expectation that a completely specific electrode utilizing faradaic electrochemistry will be developed—for example, one which would differentiate DA from NE.

Graphene has some of the properties of graphite, but they are more exaggerated. For example ... [Pg.93]

The properties of graphite intercalation compounds fulfill many requirements for advanced chemical power sources, i.e. the electrochemical cells which convert the energy released by chemical reactions directly into... [Pg.670]

Tables 5 and 6 describe other parameters that have a direct effect on the properties of graphite materials. Table 5 illustrates the difference in material properties of graphite from two different manufacturers that reflects differing raw materials and processing methods or techniques. As can be seen from Table 5, the manufacturer has a profound influence on graphite properties due to differing manufacturing procedures, proprietary methods, and processes. This is primarily why there is no industry-wide standard for carbonaceous refractories.
