Processing of Al2O3/SiC nanocomposites—part 2: green body formation and sintering

Processing of Alumina and Corresponding Composites

“…It has also been found that pH adjustment can be used to induce flocculation of the slurry, preventing segregation and agglomeration of the silicon carbide particles (Borsa et al, 1997;Walker et al, 1994). Pressure filtration has also been proposed as a means to maintain the same quality of dispersion as that of the slurry in the mixed dried powder (Timms, Ponton, & Strangwood, 2002).…”

Sintering behavior of titanium–titanium nitride nanocomposite powders

“…A few investigators [19][20][21][22][23][24][25] have discussed the effect of nano dispersion on densification, of which most indicate a decrease in the densification level with nano dispersion. Investigators [5,26,27] have reported the use of sintering aids to improve the densification of nanocomposites.…”

Dilatometric sintering study of titanium–titanium nitride nano/nanocomposite powders

“…Interparticle friction and the tendency for agglomeration are also higher as both the powders are nanocrystalline. 10,11 Although several studies have been conducted on the densification of nanocomposites, 7,[12][13][14][15][16][17][18][19][20][21] there is scarce work available on the densification of nano/ nanocomposite powders. The present investigation aims at studying the sintering behaviour of titanium-titanium nitride nano/nanocomposite powders by dilatometry.…”
