·Discrete element method DEM is used to study the factors affecting agglomeration in three dimensional copper particle systems during solid state sintering A new parameter is proposed to characterize agglomeration The effects of a series of factors are studied including particle size size distribution inter particle tangential viscosity temperature
·Coagulation by simultaneous agglomeration and sintering takes place at high temperature environments where sintering and collision rates are comparable The effect of temperature on aggregate mobility and gyration radii particle morphology and collisional enhancement is elucidated The ratio between the characteristic sintering time and
·Sintering of powders is a common means of producing bulk materials when melt casting is impossible or does not achieve a desired microstructure and has long been pursued for nanocrystalline
·Explore agglomeration processes and sintering kinetics how temperature pressure and time influence particle bonding In this article we will look at the phenomenon of agglomeration and what Agglomeration processes in sintering kinetics entail Agglomeration involves bonding particles to create more substantial and unified structures
·SCIENTIFIC REPORTS ã 2541 01 020 1 The agglomeration coalescence and sliding of nanoparticles leading to the rapid sintering of zirconia nanoceramics
·The range of measured sintering temperatures was 780 1000 °C For samples that did not show any agglomeration the sintering temperatures of both laboratory ashes and PFBC ashes were similar However PFBC samples that showed agglomeration had a higher sintering temperature than the corresponding lab ashes
·Fig 17 shows the sintering and agglomeration mechanism of the CMTF oxygen carrier particles during the cycling process At the early stage of cycling the particles fluidized well and the reactive reaction area was increased during the cycling process and the reaction performance of the particles was gradually enhanced
Sintering is an agglomeration process that fuses iron ore fines fluxes recycled products slag forming elements and coke The purpose of sintering is to obtain a product with suitable composition quality and granulometry to be used as burden material in the blast furnace This process is widely studied and researched in the iron and
·This agglomeration/sintering behavior has also been observed in reactors such as fluidized beds that promote solid mixing and good mass/heat transfer [9] Consequently improper fluidization involving channeling or even de fluidization occurs which hinders the process efficiency For an effective design of fluidized bed DRI it is therefore
