Hydrothermal Reaction Sintering of High Density Sintered Oxides

1989
Hydrothermal Reaction Sintering is one of methods to produce high density oxides ceramics. Oxide formation occurs between metal and high temperature and high pressure solutions at certain temperature, pressure and time. $$ Me + {H_2}O \to Me{O_X} + {H_2} $$

Microstructure of cBN-diamond sintered compact prepared by reaction sintering

Journal of Materials Science, 1991
cBN-diamond composite sintered compacts (diamond content 15–70 wt %) were prepared by reaction sintering at 7–7.5 GPa and 1400–1700 °C for 10–30 min from the starting powder of the hBN-diamond system in the presence of 1 wt % NH4NO3 as a volatile catalyst. A fully dense sintered compact with 99% conversion from hBN to cBN was obtained at 7 GPa and 1700

Reaction sintering of Fe-Al-Si alloys

Journal of Phase Equilibria, 2002
The present study concerns the production of multiphase alloys of the Fe-Al-Si system using a powder metallurgical approach. Several compositions have been considered based on α-Fe, α′-FeAl; and α″-Fe3Al intermetallic phases. Elemental powder mixtures were compacted and sintered in a dilatometer.

Reaction process during relative sintering of NiAl

Journal of Materials Science, 1998
Nickel aluminide compounds were synthesized by the thermal explosion mode of the self-propagating high temperature synthesis (SHS). The effects of green density and heating rate on the combustion characteristics and the microstructure of the products were studied. It was found that the combustion can not be ignited with heating rates lower than 5 K min-

Hydrothermal Reaction Sintering of Oxides

1989
Metal powders or chips were reacted with high temperature and high pressure solution to form oxides under certain hydrothermal conditions. $$ Me + X{H_2}O \to Me{O_X} + X{H_2} $$ (1) Well sintered oxide body was obtained at 1000°C for 3 to 15 h under high pressure of 100 MPa.

Reaction sintering and its practical application

Glass and Ceramics, 1993
Some important premises in reaction sintering, which compacts ceramics due to chemical reactions accompanied by a positive volume effect were examined. A calculated and graphic interpretation of the process was given and can be used to predict compaction in reaction sintering.

Solid State Reactions and Sintering

2019
Solid state reactions are mainly used to synthesize fine raw particles and to sinter advanced ceramics. To control the powder characteristics and sintering process, several analyses have been conducted based on classical thermodynamics and kinetics.
