Temperature evolution during field activated sintering
Materials Science and Engineering: A, 2004Experiments 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, 1963Studies 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, 1987Abstract 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, 1998Abstract 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, 2006Abstract 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.

High Temperature Sintered Powder Metal Parts
SAE Technical Paper Series, 1990<div class="htmlview paragraph">High temperature sintering of ferrous powder metal parts, i.e., sintering above the conventional temperature range of 2050-2100F, can provide improved physical and mechanical properties, a widening scope of unique material systems, and new opportunities for growth of the P/M industry. Three specific aspects of this

Minimum Sintering Temperatures of Fluidizable Particles
Particle & Particle Systems Characterization, 1984AbstractExperimental methods to determine minimum sintering temperatures of a variety of granules such as polymers, glass, coal, inorganic salts, etc. are presented. These methods include the use of a dilatometer in which the contraction‐dilation characteristics of a small sample is measured, a differential scanning calorimeter test and an Instron ...

The high-temperature sintering of tungsten
Soviet Powder Metallurgy and Metal Ceramics, 1965A study was made of the effect of high-temperature sintering on the shrinkage, density, porosity, chemical composition, grain size, grain density, electrical conductivity, hardness, and strength of VA tungsten bars with silicon-alkali and aluminum additions and VCh tungsten bars without additions.
