Sintering and agglomeration of Fe2O3-MgAl2O4

2020-4-1  Sintering is a physical process due to crystallite growth, and agglomeration is the cohesion of neighboring particles. Two factors may be associated with this improvement: the higher specific surface areas of oxygen carriers with low ratio of Fe 2 O 3 and higher

sintering and agglomeration -

Sintering Sintering, also known as frittage, is a thermal agglomeration process during which the atoms within the materials diffuse and form bridges across distinct particles, joining them together. Sintering involves heating products without melting them, and as such is particularly well-suited for materials with very high melting points.

2020-1-9  However, the deactivation caused by sintering and agglomeration worsens, which is an essential issue to be solved. In this study, the stability of Fe 2 O 3 -MgAl 2 O 4 oxygen carriers was investigated not only in a packed bed reactor but also a fluidized bed reactor using CO as fuel and air as oxidant at 850 °C.

2005-1-1  It was found that coals with higher proportions of calcium aluminosilicate showed higher propensity for agglomeration and defluidisation. The pressure-drop sintering technique can predict the agglomeration propensity for coals. Samples with a sintering temperature lower than the operating temperature of the PFBC showed agglomeration.

Agglomeration and sintering in annealed FePt

In this work we give a detailed account of complementary small angle neutron scattering and x-ray diffraction studies of polymer mediated, self-assembled FePt nanoparticle arrays as a function of annealing temperature. The combination of these two techniques provides significantly greater physical insight than is available using either individually.
