Sintered scanning electron microscopy images

FIGURE 22.11 Scanning electron microscopy image of sintered membrane surface fouled with WPC deposits. (From Bird, M.R. and Barttlett, M., J. Food Eng., 53, 143, 2002. With permission.)... 

Figure 1.17 Scanning electron microscopy image of the 8 mol% Ce02-stabilized ZrOz ceramic after spark plasma sintering [210].

Figure 11.16 Scanning electron microscopy images of WC crystals after leaching out Co liquid phase from (a) WC-30Co and (b) WC-3OC0-IVC (all in wt%). Both specimens were sintered at 1500°C for 72 h (from Ref [73]) (c) HRTEM image of the precipitates on (0001) habits in WC-12Co-0.5VC and (d) concentration...

Figure 16.15 Scanning electron microscopy images of polished and etched surfaces for (a) sintered reaction-bonded silicon nitride (SRBSN) from a fine silicon powder (b) SRBSN from a coarse Si powder (c) Sintered silicon nitride from a commercial fine-grained a-Si3N4 powder. All of the specimens were doped with...

Figure 12.9 Scanning electron microscopy images of sintered nano-HA, sintered at (a) 1000 and (b) 1100°C for 30min in a 3kW commercial 2.45 GHz microwave.

Microstructure of bulk samples was study by scanning electron microscopy (SEM). Images of the sintered bars at 1300°C are shown in Fig. 4. 

When pressing, the paste can be molded by applying isostatic pressure to obtain a flat product or uniaxial if tubular membranes are required. Sometimes a thermal treatment is simultaneously applied followed by a final sintering. A scanning electron microscopy (SEM) image of a cordierite membrane support is shown in Fig. 6. This support was manufactured from fine cordierite particles (< 120 um in size), mixed with poly(vinyl alcohol) (PVA) (25 wt%) as binder [33]. Water was used as solvent and eliminated by drying and so the resulting paste was uniaxially pressed and heated to 300°C at 2°C/min and then kept at 300°C for 2 h to eliminate PVA. Finally, it was...
