    Creep properties of (Si–Al–O–N)SiC whisker composites

    (Si–Al–O–N) (sialon)–SiC whisker (SiCw) composites containing up to 10 mass% SiCw were prepared by hot isostatic pressing. The strengths and the fracture toughness of composites remained relatively unchanged with...

    Influence of calcium content on the preparation of the high T c (110 K class) Bi-Pb-Sr-Ca-Cu-O thin film

    The Bi-Pb-Sr-Ca-Cu-O thin films with various Ca/Sr ratios were prepared by r.f. magnetron sputtering using multi-targets (Bi0.5Pb0.50x, CaCu0.750x, SrCu0.75Ox. The high T c phase (2223 phase) was obtained by firi...

    Electrical properties of ceramics in the system Li2O-ZnO

    The electrical properties of poly-phase ceramics in the system Li2O-ZnO were studied. The specimens obtained were confirmed to be composed of Li2ZnO2, ZnO and some Li4ZnO3, by X-ray diffraction. Li2ZnO2 was assum...
