Opis

This volume constitutes the Proceedings of the November 7-9, 1977 Conference on PROCESSING OF CRYSTALLINE CERAMICS, held at North Carolina State University in Raleigh. It was the Fourteenth in a series of "University Conferences on Ceramic Science" initiated in 1964 and still coordinated by a founding group of four ceramic related 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. In addition, two other ceramic-oriented schools, the University of Florida and Case-Western Reserve University, have also hosted Conferences in the series. These research-oriented conferences, each uniquely concerned with a timely ceramic theme, have been well attended by audiences which typically were both inter national and interdisciplinary in character; their published Proceedings have been well received and are frequently cited. This three day conference was concerned with (a) scientific aspects of all process steps which must be combined and controlled effectively and sequentially in producing crystalline ceramics (both oxides and nonoxides), and (b) utilization of these principles in developing processes for several classes of advanced ceramics critical to present and future technology."
