Most of densification occurred under nonisothermal conditions. High densification rates observed are related to a change in the internal structure of the compact. The formation of a dense outer alumina layer controlled the heat flux to the interior of the compact, and increased the amount of energy available for sintering. Sintering in fast firing occurred as a densification front moving from the outer surface toward the sample center. As long as the rate of heat transfer is enough to sustain its advance, no differential densification occurs. © 2011 The American Ceramic Society.en1744-74022011614861493Wiley-BlackwellPhysikChemieJournal Article10.1111/j.1744-7402.2011.02609.xOther
