Abstract
A process for producing a ceramic sinter or inorganic film in which anisotropic particles or anisotropic crystals have been oriented; or a process for producing a bonded composite material which comprises a base sample and another material tenaciously bonded to a surface of the base. The processes are characterized by imposing a centrifugal force during buming (heating).
Claims5
A method for manufacturing a ceramic sinter in which ceramic particles are oriented, comprising sintering a ceramic molded article containing ceramic particles with anisotropic shapes, imposing a centrifugal force during the sintering step on the ceramic particles with anisotropic shapes, in the latter stages of sintering by holding the particles on a base substrate formed on the peripheral portion of a disc or rotor to manufacture a ceramic sinter in which the particles are oriented.
A method for manufacturing an inorganic film with oriented particles, comprising forming a precursor film on a single crystal substrate or on a substrate on which a metal or ceramic has been vapor-deposited, heating the film, and imposing a centrifugal force during the heating step on anisotropic particles which are present in the precursor film by holding the film on the substrate formed on the peripheral portion of a disc or rotor to manufacture an inorganic film with oriented particles.
A method for manufacturing a ceramic sinter or inorganic film in which particles are oriented, said method comprising:
- imposing a centrifugal force on a material in which anisotropic particles are present, by holding the material on a base substrate formed on the peripheral portion of a disc or rotor during a sintering step in manufacturing the ceramic sinter or during a heating step in manufacturing the inorganic film.
