It is noted in Sections XVII-10 and 11 that phase transformations may occur, especially in the case of simple gases on uniform surfaces. Such transformations show up in q plots, as illustrated in Fig. XVU-22 for Kr adsorbed on a graphitized carbon black. The two plots are obtained from data just below and just above the limit of stability of a solid phase that is in registry with the graphite lattice [131]. [Pg.650]

Other pigments are consumed in considerably smaller amounts. Moreover, the market data for these pigments are not as readily available as those for carbon blacks, titanium dioxide, and iron oxides. [Pg.7]

Two data points in the graph lie significantly off the line and represent the N-330 carbon black mixed with QDI. These results are exceptionally good and follow from principles expected. Viscosity is known to increase as the surface area of the carbon black increases (the particle size... [Pg.494]

It was found in the 1960s that disperse platinum catalyst supported by certain oxides will in a number of cases be more active than a similar catalyst supported by carbon black or other carbon carrier. At platinum deposits on a mixed carrier of WO3 and carbon black, hydrogen oxidation is markedly accelerated in acidic solutions (Hobbs and Tseung, 1966). This could be due to a partial spillover of hydrogen from platinum to the oxide and formation of a tungsten bronze, H WOj (0 < a < 1), which according to certain data has fair catalytic properties. [Pg.539]

Small-angle X-ray scattering (SAXS) data have made it possible to deduce the localisation of organic additives (pigments) in the bulk of isotactic polypropylene (iPP) [344]. This work has confirmed that the additives are located in the amorphous phase, in spite of their crucial influence on the formation of the crystalline phase of iPP. SAXS has also been used to study the 3D structure of different carbon-black aggregates, and silica-filled SBR rubber compounds [345]. [Pg.648]

Fig. 33. Variation of dimensionless radius with dimensionless time for compact carbon black particles suspended in silicone oil undergoing a simple shear flow. Top Data for initial radius Ho 1.7 mm for different viscosities and different shear rates, but with Fa = 0.28. Bottom Data for initial radius R0 = 2.0 mm for different densities and different shear rates, but with Fa 0.28. For all cases the erosion rate constant kc = 0.37. (See Eq. 53). Fig. 33.

EDITOR S NOTE (1) The mixing of carbon black was carried out on a two-roll mill. The dispersion of carbon black in the compounded recipes was not evaluated. (2) X-ray studies of the copolymers by the author are in progress. (3) GPC data are relative and may not be comparable to those obtained with commercial instruments. [Pg.212]

In studies conducted at the 1TRI, rats were exposed to 3.5 and 10 mg particles/m air of either F.lftex 12 carbon black or diesel exhaust. These exposures were 7 h/day, 5 days/wk for 12 wk (Wolff et al. Inhal. Toxicol., in press Bond et al. In Assessment of Inhalation Hazards Integration and Extrapolation Using Diverse Data. 1989, in press). Dosimetry (mg particles/g lung), microdosimetry (DNA adducts), pulmonary inflammation, and histopathology of the lungs of... [Pg.59]

In the US in the 1970s when the GRAS list was being reviewed, safety data were requested on carbon black in view of the possibility that it might contain heterocyclic amines. Apparently, the cost of obtaining the data was higher than the entire annual sales of food grade carbon black so the tests were never done. Carbon black is not permitted in the US. [Pg.202]

With appropriate choices of kinetic constants, this approach can reproduce the NSC experimental data quite well. Park and Appleton [63] oxidized carbon black particles in a series of shock tube experiments and found a similar dependence of oxidation rate on oxygen concentration and temperature as NSC. Of course, the proper kinetic approach for soot oxidation by 02 undoubtedly should involve a complex surface reaction mechanism with distinct adsorption and desorption steps, in addition to site rearrangements, as suggested previously for char surface combustion. [Pg.548]
