The proceedings of the 4th International Conference on Sin tering and Related Phenomena, contained in this volume, have been broadened in scope to include the phenomena of sintering and coa lescence of catalytic materials dispersed upon refractory oxides. For it has long been recognized within the circles of chemists and chemical engineers working in the field of catalysis that one of the chief causes of the decline in heterogeneous catalytic activity and/or selectivity is, indeed sintering, or perhaps using a better term, coalescence of the supported catalytic metal and compounds thereof. Essentially catalytic deactivation by sintering is now weIl recognized as Ostwald ripening; which of course is a phenome non familiar to scientists grappling with the problem of sintering of powder compacts. The 4th Conference at Notre Dame marks the first occasion at which scientists and engineers of each discipline were assembled in the same room to exchange views on these phenome na of mutual concern. In the wake of the Conference at Notre Dame, all parties acknowledged the synergistic benefit which issued from this exchange, both at the formal and informal level. All were persuaded that signal benefits will be realized by a continuation of this collab oration in the form of future sintering conferences in which both powder metallurgists and catalytic scientists and engineers would participate.

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.

The 4th International Symposium on the Science and Technology of Sintering was held on 4-6 November 1987 in Tokyo. Among the many technical sessions was one entitled 'Session for Sintering-Case Study'. Over 200 participants heard these invited talks. Although some papers were over 20 years old, it is necessary to understand the authors' way of thinking. Since the end of the Second World War, many excellent papers related to sintering have appeared in many different academic journals. Some of these papers are still of value, and are still being read by today's students. The questions we have to ask are: Why does the scholar think this way? Why did the scholar perform his experiments? What is the mechanism of sintering? What is the liquid phase of sintering? What is the behavior of sintering additives? What is the history and development of sintering theory? This book includes these sort of historical papers and also new original papers on sintering, all of which are very important to our understanding of the subject. Several papers have been added for this English edition, which is thus more comprehensive than its Japanese counterpart. These papers were spread out in many different sources and the benefits of collecting them together in book form is obvious.

This book is addressed to a large and multidisciplinary audience of researchers and students dealing with or interested in sintering. Though commonly known as a method for production of objects from fines or powders, sintering is a very complex physicochemical phenomenon. It is complex because it involves a number of phenomena exhibiting themselves in various heterogeneous material systems, in a wide temperature range, and in different physical states. It is multidisciplinary research area because understanding of sintering requires a broad knowledge - from solid state physics and fluid dynamics to thermodynamics and kinetics of chemical reactions. Finally, sintering is not only a phenomenon. As a material processing method, sintering embraces the wide group of technologies used to obtain such different products as for example iron ore agglomerate and luminescent powders. As a matter of fact, this publication is a rare opportunity to connect the researchers involved in different domains of sintering in a single book.

In the past few years there has been rapid growth in the activities involving particulate materials because of recognized advantages in manufacturing. This growth is attributed to several factors; i) an increased concern over energy utilization, ii) a desire to better control microstructure in engineermg materials, iii) the need for 1mproved material economy, iv) societal and economic pressures for higher productivity and quality, v) requirements for unique property combinations for high performance applica tions, and vi) a desire for net shape forming. Accordingly, liquid phase sintering has received increased attention as part of the growth in particulate materials processing. As a consequence, the commercial applications for liquid phase sintering are expanding rapidly. This active and expanding interest is not well served by available texts. For this reason I felt it was appropriate to write this book on liquid phase sintering. The technology of liquid phase sintering IS quite old and has been in use in the ceramics industry for many centuries. However, the general perception among materials and manufacturing engineers is that liquid phase sintering is still a novel technique. I believe the diverse technological appli cations outlined in this book will dispel I such impressions. Liquid phase. sintering has great value in fabricating several unique materials to near net shapes and will continue to expand in applications as the fundamental attrib utes are better appreciated. I am personally involved with several uses for liquid phase sintering.
