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).

Temperature evolution during field activated sintering

Materials Science and Engineering: A, 2004
Experiments and finite element simulations have been conducted to characterize the temperature distribution in the specimen/die/punch setup and its evolution during field activated sintering. Significant temperature gradients were found in specimen in both radial and axial directions.

Low‐Temperature Sintering of Uranium Dioxide

Journal of the American Ceramic Society, 1963
Studies of the fabrication of uranium oxide fuel pellets by the low‐temperature sintering of nonstoichiometric oxide are described. Completer reversion to stoichiometric UO 2 in the sintered pellets was attained by two methods: (1) Sintering in a nitrogen atmosphere which contained a small ...

Low-temperature sintering of PZT ceramics

Ceramics International, 1987
Abstract The required sintering temperature of Pb(Zr0·52Ti0·48)O3 ceramics (abbreviated as PZT 52/48) can be lowered to about 1000°C by incorporating Li2CO3, Na2CO3 or Bi2O3. A dielectric constant of about 1000 and a planar coupling factor of between 45% and 65% are obtained in PZT 52/48 ceramics sintered at 1025°C, with added Li2CO3 and Bi2O3.

Microstructure of low-temperature sintered AlN

Materials Letters, 1998
Abstract A transient liquid-phase sintering process was applied to fabricate AlN ceramics, using Dy 2 O 3 , Li 2 O and CaO as additives. Li 2 O is important in forming liquid phase but volatile at high temperature. When Li 2 O was removed, the liquid volume diminished and then finally crystallized, resulting in powerful joint between AlN grains ...

A mechanism for low-temperature sintering

Journal of the European Ceramic Society, 2006
Abstract We explain the basic mechanism of the low-temperature sintering called reactive liquid-phase sintering. The mechanism involves the presence of a low-temperature liquid phase that must be able to directly or indirectly accelerate a reaction with the matrix phase.
