Inorganic Dielectrics Research
LOW LOSS MICROWAVE CERAMIC DIELECTRICS: Three compositions in the La203-A1203-Si02 system were hot-pressed and the electrical properties measured at several frequencies and temperatures. A study was made of the crystalline phases appearing in a number of compositions within the system. Two lanthanum silicate compounds, lanthanum aluminate and mullite were found in the various compositions. Attempts to form each lanthanum silicate compound by itself are being made in order to evaluate their electrical properties. This information will be used in attempting to tailor bodies to meet the specific requirements of this project. TRANSPARENT POLYCRYSTALLINE CERAMICS: Specimens of pure alumina were pressed and sintered using a two-fire procedure. For the initial firing, one set of specimens was fired in air and one set was fired in A. The second firing of both sets was performed in A. Bulk densities of the 2 sets of specimens were measured and compared. Specimens which were initially fired in air were less dense than those fired wholly in A. HOT EXTRUSION: The hot extrusion apparatus is described and results of 3 extrusion attempts are described. (Author)
