Pore structure of sintered and metallized iron oxide compacts
J.K. Wright,R.J. Tyler +1 more
15
TL;DR: Pore structures of sintered and metallized iron oxide compacts were investigated by mercury porosimetry as mentioned in this paper, and it was found that the pore volume of these compacts decreased with increasing sintering temperature and time, owing to the progressive elimination of the smallest pores present in the compacts.

Studies in gas-solid reactions: Part I. A structural model for the reaction of porous oxides with a reducing gas
J. Szekely,James Evans +1 more
- 01 Jun 1971
TL;DR: In this article, a structural model for describing the reaction of a porous metal oxide pellet with a reducing gas is presented, and it is suggested that the pellet is made up of a large number of grains and the overall rate of reaction is computed by summing the contributions of all these individual grains.
