    摘要: A neutral titanium dioxide colloid sol having a high stability in a neutral range and capable of forming a colorless transparent coating even when dried at room temperature is produced by mixing an acid titanium dioxide sol comprising 50 to 100 parts by weight of titanium dioxide colloidal particles and 5 to 50 parts by weight of a chelating agent for titanium ions with 1 to 50 parts by weight of an alkaline substance comprising at least one of alkali metal compounds and amine compounds, and optionally by adjusting the pH value of the liquid mixture to 5 to 10, or adjusting the pH value of the liquid mixture to 6 to 10, and then applying a deionization treatment to the mixture to thereby charge the titanium dioxide colloidal particles with negative electricity.

    摘要: A composite plated metal material having a composite coating layer with excellent adhesion and mechanical properties is produced by (1) displace deposition-plating a metal I base material with a metal II having a nobler oxidation-eduction potential than that of metal I and (2) dope-modifying the resultant metal II coating layer with a metal III-containing deposit in which metal III is different from metal II and exhibits a nobler oxidation-reduction potential than that of metal I, by using a displace deposition-plating aqueous solution containing metal III-containing compound ions.

    摘要: A metallic sliding material including at least a support member with a sliding surface and an inorganic compound coating layer formed on the sliding surface is disclosed. The sliding surface is formed from an aluminum alloy or a reinforcing material-containing aluminum alloy. The inorganic compound coating layer is formed from at least one aluminum compound, and at least one phosphorus compound, and at least one member selected from the group of molybdenum compounds, tungsten compounds, and chromium compounds. These compounds are present in such concentrations that molybdenum, tungsten, and chromium collectively constitute 2 to 48% by weight of the inorganic compound coating layer, aluminum constitutes 1 to 25% by weight of the inorganic compound coating layer, phosphorus constitutes 1 to 25% by weight of the inorganic compound coating layer, and the balance of the inorganic compound coating layer is oxygen and impurities.

    摘要: A microwave absorber in a pointed shape, including a phenol resin foam containing a dielectric loss material, is prepared by setting an incombustible sheet container of a same shape in a mold in a pointed shape, pouring the phenol resin to which the dielectric loss material is blended, and foaming and curing. As a result, a semi-incombustible or incombustible microwave absorber of high strength possessing a high microwave absorption capacity in a wideband is obtained.
