The Technology of High Temperature Ceramics

38, 50 pp. Award Lecture Presented at the Annual Symposium and Toledo Glass and Ceramic Award, January 18, 1960, Toledo, Ohio. As background for studies of refractory materials this paper deals mainly with two specific properties of materials with melting points above 1500 degrees Celsius. The materials are the metals, oxides, borides, carbon and graphite products, carbides, nitrides, and silicides. The properties are melting points and electrical resistivities. The data are given in graphical form for easy comparison. Short descriptions of preparation and other properties are given in some cases. A brief summary of the known methods of obtaining high temperatures is also given in graphical form with a note on measuring these temperatures. CONTENTS: Introduction; The Melting Point of Refractory Materials; Available Methods of Obtaining High Temperatures and How to Measure Them; The Electrical Resistivity of Refractory Materials; Conclusions.
