Triggering the Sintering of Silver Nanoparticles at Room Temperature
ACS Nano, 2010A new approach to achieve coalescence and sintering of metallic nanoparticles at room temperature is presented. It was discovered that silver nanoparticles behave as soft particles when they come into contact with oppositely charged polyelectrolytes and undergo a spontaneous coalescence process, even without heating.

A high temperature sintering furnace
Journal of Scientific Instruments, 1952A 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.

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.

Low temperature sintering of TiO2
Materials Science and Engineering, 1983Abstract 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.

Effect of sintering temperature on the characteristics of sludge ceramsite
Journal of Hazardous Materials, 2008In order to investigate the effect of sintering temperature on the characteristics of sludge ceramsite and find an optimal sintering temperature, dried sewage sludge, clay, and water glass were mixed at ratios of dried sewage sludge/clay=33% and water glass/clay=15%.

Low temperature sintering of CCTO using P2O5 as a sintering aid
Ceramics International, 2010Abstract Recent work on CCTO is directed towards decreasing its dissipation factor and further raising its dielectric constant by using different dopants. Also attempts have been made to lower its sintering temperature by adding different sintering aids so as to save energy and use low-cost electrodes (Ag–Pd or base metal) for making multilayer ...

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.

Effective Sintering Aids for Low-temperature Sintering of AlN Ceramics
Journal of Materials Research, 1999A 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
