A plasma synthesis method has been devised to produce nanosize YSZ powders with various yttria contents. The powders are synthesized by introducing a mixture of coarse-grained zirconia and yttria into an r.f. inductively coupled plasma flame. The ave

Ultrafine non-doped and yttria-doped zirconia (ZY) powders have been produced by a single-step plasma synthesis method. The amount of yttria doping was varied between 0 and about 10 mol%. The phase composition, structural parameters and morphology of

The hot press sintering of ultrafine γ-Al2O3-TiN and θ-Al2O3-TiN composites was studied. Initial materials were prepared by the hydrolysis of ultrafine AlN-TiN composite powder with the followed preheating at 450°C in vacuum and by mixing θ-Al2O3

The oxygen partial pressure - temperature phase diagram of YBCO type superconductors reported before by us showed that the YBa2Cu4Ox phase formation from Y2Ba4Cu7Oz with CuO, as well as from YBa2Cu3Oy, with CuO are oxidation reactions. The total gas
