It has been shown that sintering onset is characterized by the temperature interval 1100–1200°C for dry-technology pellets and 900–1000°C for wet-technology pellets.
In the present work, oxidation and sintering mechanisms in iron ore green pellets under non-sintering and sintering conditions were studied. The intent was to get more information about the sensitivity of the formation of duplex structures for variations in raw material fineness and in green pellet porosity. 2. Materials and methods2.1.
sintered ore and pellets. The ones charged into an EAF include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel).

Emission Optimized Sintering (EOS®) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS® uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means:
The researchers sintered hydroxyapatite powder at temperatures between 650°C and 1250°C, based upon what they knew about how temperature affects grain growth and densification, to generate bioceramic pellets. Those pellets sintered at 650°C, 850°C, and 1050°C developed an airy porous structure, with porosity decreasing with increasing ...
"As most past studies focused on pellet-type solid electrolytes, 75% of the production costs outlined by current cost projections for SSB were greatly overestimated, as they were based on high-temperature classic sintering techniques for solid electrolyte processing," Moran Balaish, one of the researchers who carried out the study, told TechXplore, via email.

The key of microwave sintering technology is microwave heating. The principle of microwave heating is to convert the electromagnetic energy of microwave into heat energy by means of electronic polarization, atomic polarization, interface polarization and dipole turning polarization. Obviously, not all materials can be heated by microwave.
pellets of defined diameter are produced. Next, the pellets are dried in the POLSHAFT dryer in order to prevent them from cracking during the preheating and sintering processes. Finally, the pellets are fed to the POLSINT high-temper-ature kiln and sintered to the high bulk specific densities that are required for first-class refractory products.

Flash sintering (FS) is a field-assisted sintering technique, which uses direct application of an electric field to a pellet to shorten production timescales. Rapid heating takes place due to the direct dissipation of heat in the ceramic body, enabling lower furnace temperatures than in conventional sintering.
