Lithium composite metallic oxide and production process for the same

Provided is a composite nanometal paste which, when a layer of the paste interposed between upper and lower bodies is sintered in an inert gas under no load until the layer turns to a metal layer, attains a shear bond strength between the upper and lower bodies of 10 MPa or higher. The composite nanometal paste contains, as metallic components, composite metallic nanoparticles comprising metal cores with an average particle diameter of X (nm) and an organic coating layer formed around the circumference, metallic nanofiller particles having an average particle diameter of d (nm), and metallic filler particles having an average particle diameter of D (nm), and satisfies the first relation X&#x3c;d&#x3c;D and the second relation X&#x3c;d&#x3c;100 (nm). Furthermore, this is a composite nanometal paste in which said average particle diameter d has a size such that said metal nanofiller particle can be embedded into a three pocket formed when said three said metal filler particles are placed on a plane so as to be mutually in contact, and said average particle diameter X has a size such that the gaps that remain within said three pocket are filled.

A pressure vessel of the present invention is such that at least part thereof comprises a metallic composite materialcomprising alight metal, which is turned into a matrix, and a plateshaped iron-basedmember, which is buried in the light metal, whose major component is iron, and which is provided with a large number of through holes penetrating the front and rear surfaces. By means of this construction, it is possible to provide a pressure vessel having a novel construction whose pressure resistance is enhanced without being accompanied by thickening, and a compressor being provided with a housing comprising the pressure vessel. Moreover, a casting process of the present invention is a casting process, which is suitable for producing cylinder blocks, and is characterized in that, in a casting moldbeing provided with hollow portions () forming a molding cavity surface, and a pouring passagewhich is communicated with the hollow portions, a substantially cylindrical iron-based memberhaving cut-offsat the opened end portions is allocated so that the opened end portions are brought into contact with the molding cavity surfaceand spacesare provided on the front- and rear-surface sides of the iron-based member, and a light-metal molten metal' is filled into the entire hollow portions through the pouring passagevia the cut-offs, thereby casting the light metalaround the iron-based-member
