    Abstract: Conductive past used when a wiring circuit is formed on a board, and a wiring board obtained by using the conductive paste. Since conductive paste formed by scattering metal powder and glass frit into an organic vehicle is spread onto a board by screen printing or the like and then is dried and sintered to be able to form a good-conductivity wiring circuit, it is widely used in electronic apparatus components. This paste poses problems that high contents of metal powder and glass frit with respective to the entire conductive paste will increase the viscosity of the conductive paste, for example, decrease the discharge amount of conductive paste through openings in a screen printing plate at screen printing, and that low contents will increase shrinkage at drying and sintering. The above problems are resolved by conductive paste having the above contents of at least 85 wt.%, and a viscosity of 100 through 400Pa.s when measured with an E type rotary viscosimeter at 25°C at a rotation speed of 1 rpm.

    渡,以及使用导电性糊剂而得到的布线基板。 由于通过丝网印刷等将金属粉末和玻璃料散射形成的导电性糊料通过丝网印刷等涂布在基板上,然后进行干燥烧结以形成良好的导电性布线电路,因此广泛用于电子 设备组件。 这种糊料存在的问题是,与导电浆料的整体相应的金属粉末和玻璃料的含量会增加导电浆料的粘度,例如,通过丝网印刷在丝网印刷板上的开口减小导电浆料的排出量, 并且低含量将增加干燥和烧结时的收缩。 上述问题由具有上述含量至少为85重量%的导电膏,并且用E型旋转粘度计在25℃下以1rpm的转速进行测量时,其粘度为100至400Pa.s。

    Abstract: A method for producing a metal powder wherein an ion of the metal to be precipitated is reduced by the action of a reducing agent in a liquid reaction system to precipitate the metal powder, which comprises reducing the ion of the metal under a condition wherein the exchange current density of an oxidation-reduction reaction between the ion of the metal and the reducing agent, which is determined by the hybrid electric potential theory, is 100 muA/cm2 or less, to precipitate the metal. The method allows the production of a metal powder having a reduced particle diameter.

    Abstract: A metallic colloidal solution (a) includes a water-based dispersion medium that is easy in handling with regard to safety and environment and metallic particles having a uniform particle diameter and being excellent in properties such as conductivity and (b) has properties suitable for various printing methods and ink-applying methods. In addition, an inkjet-use metallic ink incorporating the metallic colloidal solution has properties suitable for the inkjet printing method. The metallic particles are deposited by reducing metallic ions in water and have a primary-particle diameter of at most 200 nm. The dispersion medium is made of a mixed solvent of water and a water-soluble organic solvent. The metallic particles are dispersed in the dispersion medium under the presence of a dispersant having a molecular weight of 200 to 30,000.
