A Review of Ceramic Sintering and Suggestions on Reducing Sintering Temperatures

Advanced Performance Materials, 1997
Theories and applications associated with sintering of ceramics and reducing of sintering temperature are reviewed. The whole sintering process is divided into three sub-processes as powder preparation, compaction and sintering, and each sub-process is discussed in terms of its possible contribution to the reducing of sintering temperature.

On the confluence of ultrafast high‐temperature sintering and flash sintering phenomena

Journal of the American Ceramic Society, 2023
Abstract Ultrafast high‐temperature sintering (UHS) and flash sintering are novel methods for rapid sintering of ceramics, often completed in just a few seconds. Here, we show that both also share two additional features: an abrupt rise in electrical conductivity, which is electronic, and electroluminescence.

A high temperature sintering furnace

Journal of Scientific Instruments, 1952
A laboratory furnace is described in which specimens 75 mm long by 15 mm diameter can be heated to 2 400° C either in hydrogen or in a vacuum better than 10-4 mm of mercury. The electrical-resistance heater is a fabricated tungsten tube 150 mm long by 35 mm diameter.

Low temperature sintering of TiO2

Materials Science and Engineering, 1983
Abstract Low temperature sintering was achieved in ultrafine, well-dispersed and uniformly packed TiO2 powder compacts. TiO2 powder was prepared by hydrolysis of titanium isopropoxide, calcination at 550°C and dispersion in an aqueous solution with a controlled pH value.

Low Temperature Sintering of Innovative Bioactive Glasses

Journal of the American Ceramic Society, 2012
Two innovative glass compositions based on the commonly used 45 S 5 B ioglass ® were developed by increasing the calcium quantity and replacing the sodium oxide with a specific content of potassium oxide.

Effective Sintering Aids for Low-temperature Sintering of AlN Ceramics

Journal of Materials Research, 1999
A disappearing sintering aid was used to promote densification during the initial and middle stages of sintering and to be removed in gaseous form from the specimens during the final stage of sintering. From thermodynamic consideration such as assessment of Gibbs free energy change of formation of Al2O3 compounds including metal-oxide and evaluation of

Low-temperature sintering of ZrW2O8–SiO2 by spark plasma sintering

Journal of Materials Science, 2009
Amorphous ZrW2O8 powder and amorphous SiO2 powder were prepared by a sol–gel process as raw materials, and high-density ZrW2O8–SiO2 were successfully prepared at a much lower temperature of 923 K for a much shorter holding time of 10 min by spark plasma sintering (SPS) method rather than by conventional melt-quenching method.

Temperature–Pressure‐Sintering (TPS) diagram approach for sintering of silicon

Materials Letters, 2012
Abstract Temperature–(water vapor) Pressure‐Sintering (TPS) diagrams were established to control the microstructure evolution and densification during sintering of silicon. Experiments were performed under controlled humidified atmospheres and corroborated diagram predictions.

High Temperature Sintered Interconnects Formed by Transient Liquid Phase Sintering

International Symposium on Microelectronics, 2013
Low Temperature Transient Liquid Phase Sintering (LT-TLPS) enables the formation of joints robust to high temperatures at low process temperatures. TLPS systems consist of one or more low temperature constituents (i.e. Sn) and one or more high temperature constituents (i.e. Cu).
