Emergent Process Methods for High-Technology Ceramics

This volume constitutes the Proceedings of the November 8-10, 1982 Conference on EMERGENT PROCESS METHODS FOR HIGH TECHNOLOGY CERAMICS, held at North Carolina State University in Raleigh. It was the nineteenth in a series of "University Conferences on Ceramic Sci­ ence" initiated in 1964 by four institutions of which North Carolina State University is a charter member, along with the University of California at Berkeley, Notre Dame University, and the New York State College of Ceramics at Alfred University. More recently, ceramic­ oriented faculty in departments at the Pennsylvania State University and Case-Western Reserve University have joined the four initial institutions as permanent members of the consortium. These research­ oriented conferences, each uniquely concerned with a timely ceramic theme, have been well attended by audiences which typically were both international and interdisciplinary in character; their published Proceedings have been well received and are frequently cited. This three day conference addressed the fundamental scientific background as well as the technological state-of-the-art of several novel methods which are beginning to influence present and future directions for non-traditional ceramic processing, thus affecting many of the advanced ceramic materials needed for a wide variety of research and industrial applications. The number, the importance and the application of new ceramic processing techniques have expanded considerably during the last ten years.
