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. $$ Me + {H_2}O \to Me{O_X} + {H_2} $$

Reaction sintering of zircon–dolomite mixtures

Journal of the European Ceramic Society, 2001
Abstract Dolomite–zircon mixtures have become interesting for finding alternate sources to improve the production of high magnesia refractories. To asses this option, two minerals, dolomite and zircon were selected, as economically raw materials, to produce MgO–CaZrO 3 –Ca 2 SiO 4 materials.

Effect of atmosphere on the reaction sintering of Si2N2O

Ceramics International, 1989
The reaction sintering of Si2N2O from an equimolar mixture of Si3N4 and SiO2 with 5 wt% Al2O3 addition was investigated in 98 or 980 kPa N2 at 1600–1850°C. At the initial stage, Si3N4 densification occurred through a liquid phase of SiO2Al2O3 system. Further densification was observed together with the formation and exaggerated grain growth of Si2N2O.

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.
