PREFACE
The Sixth International Conference on Sintering and Related
Phenomena took place at the University of Notre Dame, Notre Dame,
Indiana June 6-8, 1983. This conference was also the twentieth
Conference on Ceramic Sciences organized yearly by a "confederation"
of four institutions: North Carolina University at Raleigh, N.C.,
the University of California at Berkeley, CA, Alfred University at
Alfred, NY and the University of Notre Dame, Notre Dame, IN.
The papers presented at the last Notre Dame conference collect-
ed in this volume, reflect the progress in our understanding of the
process of sintering achieved in the past four years.
It seems that the analysis of the two particle models is
finally extended to the analysis of the models of compacts. In
these investigations strong emphasis is put on pore-grain boundar-
ies interaction which appear to be central to this problem. It is
to be hoped that in the near future an adequate model of the compact
will be developed which may serve as a useful basis of powder tech-
nology. Also, the effects of atmosphere on the sintering of ceramics
after a long period of neglect, seem to attract the attention of
more workers in the field.
During the 1975 Conference at Notre Dame, chemical engineers
and chemists working in the field of catalysis, joined our discussions
for the first time. The volume of proceedings of that particular
conference was aptly entitled "Sintering of Catalysis." This col-
laboration persists and in the recent converence we had a special
session on Sintering of Catalysts, attended by the best scientists
working in the field.
We wish at this point to express our gratitude to the National
Science Foundation, Division of Materials Research for their support
under grant DMR-83099l6 and to the Department of the Army, U. S.
Army Research Office, Metallurgy and Materials Science Division for
their support under grant DAAGZ9-83-M-OZ6Z.

It should be noted that the views, op~n~ons, and/or findings
contained in these conference proceedings are those of the authors
and should not be construed as an official Department of the Army
position, policy, or decision unless so designated by other documen-
tation.
Due to the grants of these agencies, more students could take
part in this conference than at any previous conferences.
Our gratitude is due to all participants and especially to
those authors who have sent their manuscripts early enough so that
they could be included in this volume.
It is our pleasant duty to thank all our students who helped
in performing various tasks during the conference. Special thanks
are due to Mrs. J. Peiffer and Miss Tina Widerquist for their help
in editing the conference papers.
