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

Abstract

Effort was made to study techniques and compositions for producing radome materials which can be fabricated at temperatures considerably below their use temperature and yet maintain all desirable engineering properties. The high alumina bodies were evaluated that were fabricated with magnesium carbonate and magnesium fluoride as sources of magnesium oxide. Aluminum oxide-oxychloride was substituted for the alumina in a high alumina body which resulted in a very high density body. The role of grain growth inhibitors and promoters in alumina compositions is investigated. (Author)
