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

Abstract

Attempts were made to develop refractory ceramics for radomes that can be processed at temperatures considerably lower than their maximum use temperature. High alumina bodies containing 94 and 96% Al2O3, were developed with excellent engineering properties when matured in the range 2600 to 2800 F. The low maturing temperature and the excellent physical properties of these bodies were attributed to a presintering process. Studies were initiated on the mechanisms that enable a presintered body to mature at lower temperatures with superior physical properties. The incorporation of a devitrifiable glass in an alumina matrix and the total fritting of a refractory composition were also investigated. (Author)
