DEVELOPMENT OF REFRACTORY CERAMICS THAT CAN BE PROCESSED AT TEMPERATURES CONSIDERABLY LOWER THAN THEIR MAXIMUM USE TEMPERATURE

Abstract

Cordierite compositions were prepared utilizing the fritted composition as the basic raw mate rial. Density, moisture absorption, X-ray determinations, thermal expansion, and transverse strength results are shown. A study of the densification of six compositions in the alumina magnesia system was carried out in vacuum, dry hydrogen and dry helium. The compositions range from pure alumina at one end to a 2.0% magnesia content at the other end. Density and moisture absorptions are shown as a function of the composition and firing atmosphere.
