FOREWORD
The International Thermal Conductivity Conference was started
in 1961 with the initiative of Mr. Charles F. Lucks, who passed
away on 8 July 1982 and to the memory of whom this volume is
dedicated.
These Conferences on thermal conductivity grew out of the
needs of researchers in the field. The Conferences were held annu
ally from 1961 to 1973 and have been held biennially since 1975
when our Center for Information and Numerical Data Analysis and
Synthesis (CINDAS) of Purdue University became the Permanent
Sponsor of the Conferences. These Conferences provide a broadly
based forum for researchers actively working on the thermal conduc
tivity and closely related properties to convene on a regular basis
to exchange their ideas and experiences and report their findings
and results.
The Conferences have been self-perpetuating and are an example
of how a technical community with a common purpose can transcend
the invisible, artificial barriers between disciplines and gather
together in increasing numbers without the need of national pub
licity and continuing funding support, when they see something
worthwhile going on. It is believed that this series of Conferences
not only will grow stronger, but will set an example for research
ers in other fields on how to jointly attack their own problem
areas.
Of the first thirteen Conferences, only four published formal
volumes of proceedings. However, effective with the Fourteenth
Conference, a policy of publishing formal volumes of proceedings
on a continuing and uniform basis has been established. Thus,
including the present volume, the following formal volumes of pro
ceedings have been published:

Dr. T. Ashworth, Chairman of the Eighteenth Conference is to
be congratulated for his excellent leadership in conducting the
Conference; the painstaking efforts of Dr. Ashworth and his co
editor, Dr. David R. Smith, made the present volume possible.
CINDAS looks forward to working with future host institutions to
ensure that future Conferences continue to produce high-quality
volumes of proceedings in this important. specialized field.

PREFACE
The 18th International Thermal Conductivity Conference (ITCC)
was held at the Rushmore Plaza Civic Center, Rapid City, South
Dakota on 3 - 5 October, 1983. It was hosted by the South Dakota
School of Mines and Technology (SDSM&T); the conference chairman
was T. Ashworth. RE/SPEC Inc. of Rapid City was a sponsor of the
conference, with continuing sponsorship from CINDAS/Purdue
University. In addition to the chairman, the other local committee
members were
D. R. Smith, SDSM&T
E. Ashworth, SDSM&T
W. B. Krause, RE/SPEC Inc.
J. D. Patterson, SDSM&T
R. D. Redin, SDSM&T
A. H. Redin, Spouses Program.
Papers presented covered a wide range of aspects of thermal
conductivity; special sessions were organized on glassy materials,
insulations, the high-temperature flash-laser method, and geologic
materials. Following welcomes by D. L. McElroy, Chairman of the
International Thermal Conductivity Conferences, R. A. Schleusener,
President of SDSM&T, Arthur P. LaCroix, Mayor of Rapid City, and
Paul F. Gnirk, President of RE/SPEC Inc., the technical portion of
the conference began with a Keynote Address by M. H. Cohen (EXXON)
on "Metastable Liquids and the Nature of the Glass Transition".
This was followed by an invited paper by R. Berman (Oxford University)
entitled "Solid Helium: A Review". Additional invited papers
(G. K. White (CSIRO) on "Lattice Thermal Conductivity at Normal and
High Temperature"; G. A. Slack (GE) on "Pressure Effects on Thermal
Conductivity"; P. G. Klemens (University of Connecticut) on "Theory
of the Thermal Conductivity of Amorphous Solids"; R. Taylor (UMIST)
on "Thermal Diffusivity of Layered and Fibrous Composites";
G. W. Milton (Cornell University) on "Estimating the Thermal
Conductivity of Composites") were intermingled with 81 contributed
papers. This mixture gave an enjoyable and stimulating balance
between review and research papers. For the first time a poster
ix
session was included. Eleven papers were presented in this session,
which was well attended with a high level of interest; the experiment
was deemed a substantial success.
Overall statistics for the meeting include 109 registered
delegates (75 from the U.S., 9 from Canada, and 25 from 11 countries
around the world), and 89 presentations involving 140 authors.
Additional activities included visits to the SDSM&T Physics
Department Thermophysical Properties Laboratory and RE/SPEC's
Thermomechanical Laboratories, a mid-conference tour in the Black
Hills, including Mount Rushmore, culminating in an informal banquet
at the Chute Roosters in Hill City, and a special, invited presen
tation by L. Korb (Rockwell International) on "The Space Shuttle
Orbiter Thermal Protection System"; this presentation brought the
formal business of the conference to an end.
At the banquet the Thermal Conductivity Award was presented
jointly to M. L. Minges of the Air Force Materials Laboratory,
Wright-Patterson AFB. and G. K. White of CSIRO, Australia. Also
R. U. Acton and P. Wagner, both of Sandia National Laboratories,
were elected to Fellowships of the ITCC.
On a personal note, as Chairman of the 18th ITCC, I would
like to express my appreciation to all the people who helped to
make this conference a success. In particular I would like to
extend my thanks to Dave McElroy and Jerry Hust for their
encouragement and guidance, to the session chairmen for their
services at the conference and for their help in obtaining reviews
of the papers submitted for these proceedings, to the invited
speakers for their wonderful presentations, to the members of the
local committee for their assistance, and especially to my three
main helpers, my secretary Mabel Miessner, my co-editor David
Smith and my wife, Eileen.
The next meeting in this series will be held at Tennessee
Technological University, under the chairmanship of D. W.
Yarbrough, October, 1985. I look forward to seeing you all then.
Rapid City, SD. T. Ashworth,
June, 1984 Chairman, 18th ITCC.
