As the temperature is slowly increased to 1500[degrees]F, the
aluminate and ferrite phases melt and some of the calcium oxide reacts with the silica oxide to form a calcium silicate mineral called belite.
1) demonstrated the presence of tricalcium silicate (alite) as the primary clinker phase, as postulated previously by Henri Le Chatelier [2, 3] and observed by Tornebohm [4], and also indicated phases that are now called belite (dicalcium silicate), tricalcium
aluminate, ferrite, and periclase.
The interaction of copper with the support is revealed through the formation of copper
aluminate, Cu[Al.sub.2][O.sub.4].
Along the ash separation system, the content of free CaO and other free oxides decreases as the content of silicates and
aluminates increases.
It is known that the cation disorder and nonstoichiometry of
aluminates like Mg[Al.sub.2][O.sub.4] provide a large number of lattice defects, which may serve as trapping centres.
Films of zinc
aluminate were deposited by an ultrasonic spray pyrolysis technique described earlier [22].
Spectroscopic data of synthesized
aluminates complex are reported as IR (KBr): 3380, 3315, 3225, 3010, 2958, 2874, 2735, 2360, 1950, 1475, 1382, 1158, 463, 453, 1061, 879, 885 [cm.sup.-1]; MS, m/z = 360 ([M.sup.+]), 353, 333, breda 313, 290, 279, 254, 239, 203, 184, 167, 142, 133, 121, 98, 85, 63, 50.
Materis supplies the construction industry with speciality building materials like
aluminates, admixtures, mortars and paints.
As the alkaline
aluminates are formed by solid states reactions in the solid phase (Fig.
Some chapter topics include microstructure of diverse hierarchy in silicates and
aluminates, SiOT models used to calculate the Raman spectroscopy of molten silicates, and Raman spectra of some inorganic glasses and compounds.
Mehran Rezaei, a member of academic staff at Kashan University is the researcher who has synthesized nanocrystalline magnesium
aluminates to better nickel catalyst used in methane reforming process.In this research, first magnesium
aluminate was prepared through precipitation method in presence of surface active agents.
More recent studies have dealt with the calcium
aluminates type of inclusions present in steel and their deformation behaviour during the hot working process (Faulring, and Farrell et al., 1980; Dekkers, et al., 2002; Beskow, et al., 2002; Dub, et al., 2004; Agboola, 2006).
Significant amount of water formed in the last catalytic beds during the FT synthesis is responsible for the formation of the small amounts of cobalt
aluminates in bed 3 and noteworthy amounts of cobalt
aluminates in bed 4 (Jacobs et al., 2002; Jongsomjit and Goodwin, 2002; Tavasoli et al., 2005).
