摘要 |
A highly thermoconductive ceramic substrate, which is characterized by having formed on a ceramic substrate an electroconductive coating of a mixture of tungsten and/or molybdenum with the nitride of a transition metal belonging to Group IVa of the Periodic Table of Elements. As the ceramic substrate in the present invention, a non-oxide type ceramic substrate is used because of satisfactory strength. The formation of the electroconductive coating consisted preponderantly of a mixture of tungsten and/or molybdenum with the nitride of a metal belonging to Group IVa of the Periodic Table Elements is accomplished, for example, by preparing a metallizing composition in the form of a paste or solution containing a metal salt of tungstic acid or molybdic acid and a transition metal of Group IVa or a compound thereof, applying the metallizing composition on the ceramic substrate, heating the resulting composite, then firing the composite. |
