This pointed to the fact that the thermal energy provided by the calcinations controlled the crystalline phase and particle size [34].
The starting (pristine) MWCNTs, the functionalized MWCNTs, and the hybrid MWCNT/Ti[O.sub.2] nanocomposites after calcination were characterized by X-ray diffraction, the later to evaluate the crystallinity degree of the coating.
Inorganic Si[O.sub.2] nanofibrous membrane has both flexible and high-heat-resistant properties, which can be fabricated by a combination of electrospinning with sol-gel process, followed by calcination [19, 20].
The sugar scum powder was put in a tubular furnace (Carbolite Ltd., UK) and heated at a rate of 10[degrees]C/min, held at different calcination temperatures between 400 and 1000[degrees]C during desired time, and allowed to cool to room temperature.
Highly reactive metakaolin produced by calcination of the paper sludge exhibited good pozzolanic properties and recognized its incorporation in cement systems [11].
The study focused on four modification methods; sedimentation process, chemical bleaching, calcination, and dealumination.
That is, the anatase Ti[O.sub.2] produced in the sol-gel process can likely show {001} facets after calcination. The inset in Figure 2(b) (HR-TEM of S2500) clearly shows the continuous (004) atomic planes with a lattice spacing of 0.238 nm, corresponding to the {004} planes of anatase Ti[O.sub.2] single crystals, which further confirms that the exposed crystal facet is {001} facet.
Based on the TGA results, calcination was conducted at selected temperatures for 1h duration.
SEM micrographs revealed when the temperature increased the surface morphology of the samples changes and also appears that a higher calcination temperature favors a particle with larger grain sizes.
Moreover, previous studies are shown that after calcinations at 500[degress]C, the intensity of those peaks due to PVA are decreased or almost disappeared, indicating the removal of PVA molecules from the fibers (23-25).
For the first time regularities of anthracite calcination in the electric calcinator were investigated on a physical model and a laboratory installation with visualization of the calcination process.
The sintering technologies (Stefanescu, 2000); (Stefanescu & Sandru, 1999) are conditioned by the shaping regime, the calcinations regime and the sintering regime:
