Abstract : Yttrium oxide is considered as a candidate material for the fabrication of a transparent ramjet combustor to be used for combustion research. Data from several sources is compiled to compare various processing techniques. Information is provided on yttria powder preparation, sintering techniques, and on variations such as hot forging and the use of dopants to achieve theoretical density. Mechanical properties are discussed as related to the combustor application. (Author)
