Reaction sintering of fluorine-doped MgSiN2

Journal of the European Ceramic Society, 2004
Abstract Reaction bonded MgSiN 2 (RBMSN) with CaF 2 and YbF 3 , as sintering additives was prepared by direct nitridation of Si/Mg 2 Si/Mg/Si 3 N 4 powder compact in a temperature range 1350–1550 °C. The influence of the ratio of constituents on the final phase composition, the amount of sintering additives and the influence of sintering ...

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

Microwave Reaction Sintering of Oxide Ceramics

Journal of Microwave Power and Electromagnetic Energy, 1992
A120 3-Mg0 and A1203:Zr02-Si02 mixtures were reaction sintered in a single mode cylindrical cavity applicator CMPR250 operating at 2.45 GHz in the TM012 mode to form spinel MgA1204 and Zr02 dispersed mullite matrix composites respectively. High heating rates at low power levels were achieved. Consequently, fine grain size and high density were achieved.

Reaction sintering of TiN-TiB2 ceramics

Acta Materialia, 2003
Reaction sintering of TiN with B4C addition was carried out at temperatures ranging from 1980–2020 °C. The process involves a reaction between TiN and B4C at temperatures of 1400–1500 °C resulting in the formation of fine highly active TiB2 particles uniformly distributed in a matrix of TiN. The role of extremely fine particles of TiB2 in providing the

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.

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.
