    • A composite particle for electrodes is disclosed which is formed through a granulating process wherein a conductive assistant agent and a binder are adhered to and integrated with particles composed of an electrode active material. This granulating process preferably includes a step for preparing a material liquid containing the binder, the conductive assistant agent and a solvent; a step for creating a fluidized bed of electrode active material particles by introducing the electrode active material particles into a fluid vessel; and a step wherein the material liquid is sprayed into the fluidized bed so that the material liquid is adhered to the electrode active material particles and dried thereon, and then the solvent is removed from the material liquid adhered to the electrode active material particles, thereby closely binding the electrode active material particles and particles of the conductive assistant agent by means of the binder. By using the thus-obtained composite particles as a component material for an electrode, it becomes possible to sufficiently reduce the internal resistance of the electrode. Furthermore, by using such an electrode as the anode and/or the cathode of an electrochemical device, it becomes possible to sufficiently increase the power density of the electrochemical device.

    • A ceramic product is produced by mixing a preform of metallic or ceramic fibers or a porous ceramic with at least one polysilazane (1) having a number-average molecular weight of 20 to 3,000 and a cold viscosity of less than 1 Pa.s and selected from among a polysilazane mainly comprising repeating units of the formula -[(SiH2)n(NH)r]- (wherein n and r are each 1, 2 or 3) and derivatives based thereon, such as copolymers, modified polymers and cross-linked polymers, and at least one polysilazane (2) selected from among ones having a number-average molecular weight of 200 to 100,000 and a cold viscosity of 100 Pa.s or above and solid ones, impregnating the mixture with a polysilazane-base polymer mixture having a number-average molecular weight of 200 to 3,000 and a cold viscosity of 100 Pa.s or less, hardening the resulting mixture by cross-linking, firing the same into a ceramic, and repeating these operations. Examples of the polysilazanes include inorganic polysilazane, inorganic polysiloxazane, polyorgano(hydro)silazane, modified polysilazane and polymetallosilazane. It is possible to inhibit the delamination of the fibers by applying CVD coating before or after the impregnation, hardening and firing of the preform.
