Compared to TiO2, a few of new absorption peaks are observed at 1414 cm-1, 2938 cm-1, 1726 Cm-1 and 1277 cm-1 in the spectrum of uncalcined
We investigated the effect of the calcination temperature on the photocatalytic activity of Ti[(OH).sub.4], and the results showed that the best result was achieved with uncalcined
Ti[(OH).sub.4], exhibiting 98% degradation of AML and MB under irradiation of visible light, being more than 10 times more active than Ti[O.sub.2]-COM.
XRD analysis was used to determine the crystal structure of the nanosized Zr[O.sub.x] doped MnC[O.sub.3] catalyst uncalcined
(1% Zr[O.sub.x]-MnC[O.sub.3]) and calcined at 300, 400, and 500[degrees]C.
Figure 3 shows the thermogravimetry (TG) and derivative thermogravimetry (DTG) curves of the original RM and uncalcined
20Fe/MRM catalyst precursor (the obtained precipitate dried at 105[degrees]C).
Thermogravimetric analysis (TGA) and differential thermal analysis (DTA) of uncalcined
Razor shell were shown in Figure 3.
India Petcoke CFR is CW Research's bi-monthly price assessment and monthly price index for India uncalcined
Scanning electron microscopy of uncalcined
HAP was regular and round in shape whereas of calcined powder confirmed the presence of soft agglomerates.
Recipes that are composed of saggar ash and ulexite are coded as A (uncalcined
ash and ulexite) and AC (calcined saggar ash and ulexide); glaze recipes where colemanite is a flux are coded as B (raw ash and colemanite) and BC (calcined ash and colemanite); ash component stoneware recipes are coded as C (raw ash and stoneware glaze) and CC (calcined ash and stoneware glaze).

gold/iron-oxide catalysts for low-temperature CO oxidation," Catalysis Today, vol.
The reaction of uncalcined
ZT powders and urea fuel taking place during heat treatment was investigated by thermogravimetric analysis (TGA), differential thermal analysis (DTA).
However, because they contain a proportion of uncalcined
limestone as an ingredient, blended cements have a lower environmental impact.
138) (Vicat, 1837): "We persist in thinking, as we have always maintained till now, that the lime in cements of natural or artificial pouzzolanas, as well as in cements formed with the uncalcined
psammites and arenes, enters into chemical combination with theses substances."
