  • Method for adhesion of ceramics
    Patent number: 4293356
    Abstract: A method for providing strong adhesion of two ceramic articles to each other or one ceramic article to an article of metallic copper, which method comprises applying, in the former adhesion, a powder mixture of CuS-LaCrO.sub.3 -SiO.sub.2 -Cu to the opposed surfaces of the two ceramic articles or, in the latter adhesion, a powder mixture of CuS-LaCrO.sub.3 -SiO.sub.2 to the opposed surfaces of the ceramic article and the article of metallic copper and, thereafter, heating the pair of articles in the air at a temperature of from 1000.degree. to 1200.degree. C.
    Type: Grant
    Filed: April 25, 1980
    Date of Patent: October 6, 1981
    Assignees: Agency of Industrial Science & Technology, Ministry of International Trade & Industry
    Inventors: Yoshihiro Ebata, Yasuo Toibana, Tsuneo Uetsuki, Saburo Kose, Makoto Kinoshita
  • Method for adhesion of ceramics
    Patent number: 4269641

  • Method for fast adhesion of silver to nitride type ceramics
    Patent number: 4163074
    Abstract: A thin coating of silver is formed fast on the surface of a nitride type ceramic article by coating the surface of the ceramic article with a mixture consisting of copper sulfide and kaolin, subjecting the coated article to a thermal treatment in a nitrogen-containing atmosphere at a temperature in the range of from 900.degree. to 1300.degree. C., then overcoating the thermally treated ceramic article with silver carbonate and heating the overcoated article again in the nitrogen-containing atmosphere at a temperature in the range of from 700.degree. to 900.degree. C.
