Sintering time

D = the metal dispersion at sintering time t D0 = the initial metal dispersion k = the activated kinetic rate constant of sintering n = the sintering order... [Pg.516]

The metal surface area can be used in place of the metal dispersion. The variation of k with sintering time t and thus metal dispersion D has to be known for this equation to be applied. [Pg.516]

Relationship between hardness-temperature and sintering time for a-Al203 modified with MgO (0.6%),... [Pg.86]

Rare earth oxides and Y203 are more stable than the other additives [267] no change in concentration of yttria or lanthanoide oxides has been found experimentally, even during long sintering times [232, 268, 272, 274]. [Pg.88]

Laminates were prepared by sequential filling of the die and pressing, as schematically shown in Fig. 6.4. The laminates Bl-Al (named FGM-A), B2-A1 (named FGM-B) and B3-A1 (named FGM-C) were sintered under 22 bar nitrogen gas pressure at 1800°C for 1 hour. Also, to observe the effects of sintering time and temperature, B3-A1 laminate was sintered at 22 bar nitrogen gas pressure at 1700°C for 1 hour (named FGM-D) and for 2 hours (named FGM-E). [Pg.162]

A similar sintering time sequence for TE-5070 at 350 °C is shown in Fig. 29. In 5 min there is a smoothing of the boundaries, a decrease in thickness (to about 300 A) and a corresponding increase in lateral size (to more than 1000 A) of the... [Pg.125]
