    Abstract: Thermally sprayable powders for the formation of abradable seals, and abradable seals formed by thermally spraying the powders, suitable for use with Ti alloy blades at temperatures up to 700.degree.C are disclosed. The powder includes an alloyed metal phase material and a solid lubricant type ceramic phase material. The alloyed metal phase material includes a major amount of at least one matrix metals selected from the group consisting of Ag and Cu, at least one melting point depressing metal selected from the group consisting of Si, B, Mn, and Al, and at least one oxidation resistant metal selected from the group consisting of Al, Cr, and Si. The solid lubricant-type ceramic phase material is preferably selected from hexagonal boron nitride, molybdenum sulphide, graphite, talc, bentonite or mica.

    Abstract: A single calcination stage process for the synthesis of homogeneous crystalline lithium nickel cobalt dioxide from either a mechanical mixture of nickel and cobalt oxides, hydroxide or oxyhydroxide or a chemical precipitation of a homogeneous nickel cobalt hydroxide or cobalt nickel cobalt oxyhydroxide is provided. The reactants are calcined in the presence of lithium hydroxide and an alkali metal hydroxide under predetermined oxygen partial pressure and temperature conditions. The products of the process are characterized in having a lithium to transition metal ratio closely approximating to the desired theoretical value.

    Abstract: An electroluminescent laminate is provided that comprises: a planar phosphor layer (22); a front and a rear planar electrode (14,24) on either side of the phosphor layer; a planar dielectric layer, which is preferably composed of a thick layer (18) and a thin layer (20), between the rear electrode and the phosphor layer, the dielectric layer being formed from sintered ceramic material such that the dielectric layer provides a dielectric strength S which is greater than about 1.0 X 106 V/m and a dielectric constant such that the ratio of the dielectric constant of the dielectric layer to that of the phosphor layer is greater than about 50:1, the dielectric layer having a thickness sufficient to prevent dielectric breakdown during operation as determined by the equation d2 = V/S, wherein d2 is the thickness of the dielectric layer and V is the maximum applied voltage, the dielectric layer forming a surface adjacent the phosphor layer which is sufficiently smooth that the phosphor layer illuminates generally uniformly at a given excitation voltage, and wherein the dielectric layer is either in contact with the phosphor layer or spaced apart from it by at least one additional layer that is itself in contact with the phosphor layer and wherein the layer that is in contact with the phosphor layer is compatible with the phosphor layer.
