Reaction sintering: correlation between densification and reaction

Journal of Materials Science, 1979
By studying simultaneous densification kinetics and reaction kinetics during the sintering and hot pressing of alumina-zircon mixtures, it has been possible to distinguish between the particle rearrangement and particle reshaping (diffusive) stages of the densification process. Particle rearrangement is found to be more significant during hot pressing (

Reaction Sintered LiAlON

2008
Recent results suggest that Li + can substitute for Al 3+ in the gamma-AlON structure. LiAl 5 O 8 is isostructural with gamma-AlON above 1290°C after it goes through an ordered-disordered phase transformation and has a similar lattice parameter. A previous study showed the benefits of reaction sintering LiAlON starting with LiAl 5 O 8 as compared ...

Reaction Sintering of Uranium Monocarbide

Transactions of the Indian Ceramic Society, 1975
High density (95% theoretical) single-phase uranium monocarbide has been fabricated by warm pressing a mixture of suitably sized dicarbide and uranium metal powders at 800°C at 675 kg/cm2 for 5 minutes and by subsequent sintering at 600°-1000°C. The high density and the single phase structure could be retained upto 1800°C, though some grain growth ...
