Report from IUPAC-Sponsored Symposium

10th International IUPAC Conference on High Temperature Materials Chemistry (HTMCX)
10-14 April 2000, Jülich, Germany

> Back to Calendar

The IUPAC conferences on HighTemperature Materials Chemistry were initiated by the Inorganic Division’s Commission on High-Temperature Materials and Solid State Chemistry (II.3) in 1977 and have become the premier international venue for exploring the combination of chemistry and materials science as these affect understanding, production, and use of high-temperature materials. As part of its service to the high-temperature and materials chemistry communities, IUPAC Commission II.3 has provided overall organization and continuity of the series, along with selection, coordination, and guidance of the individual-conference local organizers. This tenth conference in the series was held 10-14 April 2000 in Jülich, Germany. It was organized by Prof. Klaus Hilpert of the Forschungszentrum Jülich with the help of F. Froben and L. Singheiser. The Jülich conference provided significant opportunities for productive interchange between basic and applied researchers, with particular emphasis on applications of thermodynamics, of modern diagnostics, and of corrosion studies to the high-temperature processing and chemical behavior of bulk materials and coatings, and to high-temperature light sources.

There were about 250 papers and 250 participants from 26 countries at this highly successful, fully subscribed meeting. International participation was facilitated by a generous grant from the German Science Foundation to support attendance by scientists from the former "East". To ensure productive dialog between basic science and applications–and among industrial, research laboratory, and academic scientists–the conference, following tradition, was held with no parallel sessions and with lots of opportunities for formal and informal discussion. The majority of the papers were presented in poster sessions. In addition, there were 7 invited lectures, 17 keynote lectures, 41 shorter oral presentations, and 7 hands-on demonstrations of computerized thermodynamic databases.

Main lectures to be published in a future issue of Pure and Applied Chemistry introduced the following different topics and sessions: hydrocarbon oxidation kinetics (J. Warnatz, IWR, Heidelberg, Germany); laser vaporization for mass spectrometric studies at 3000-5000 K (J. Hastie, NIST, Gaithersburg, Maryland, USA); containerless levitation methods to produce and study high-temperature liquids (P. Nordine, Containerless Research, Evanston, Illinois, USA); thermodynamic models for use in computer databases (M. Hillert, KTH, Stockholm, Sweden); transport processes between the 1000 K wall and the 3600 K electrode in metal halide gas discharge lamps (W. van Erk, Phillips, Eindhoven, Netherlands); analysis of kinetic processes at solid-solid interfaces (H. Schmalzried, University of Hannover, Germany); and applications of chemical vapor deposition to produce tailored structural coatings (G. Wahl, Technical University Braunschweig, Braunschweig, Germany).

Keynote lectures by leaders of their fields comprised presentations discussing and using varied techniques, including high-temperature mass spectrometry, molecular beam sampling, electric-field activated combustion synthesis, synchrotron X-ray studies of levitated liquids, and gas-phase electron diffraction determination of molecular structure; a number of forefront experimental and modeling studies of ceramic materials and oxides; and studies of alloys, fullerenes, carbon nanotubes, and fuel cells. These papers, along with the other oral and poster presentations, illustrated the tremendous variety of physical and chemical techniques that are utilized, and of systems -technological and basic- that are studied under the umbrella of "high-temperature materials".

The two meetings that immediately preceded HTMC-X in this well-established and successful IUPAC series were in State College, Pennsylvania, USA (1997) and Vienna, Austria (1994). Following a pattern of meeting every three years on a different continent, the next conference, HTMC-XI, is scheduled for 2003. It will be held in Asia for the first time, in Tokyo, Japan, hosted by Michio Yamawaki of the University of Tokyo (yamawaki@q.t.u-tokyo.ac.jp).
