  • Ceramic compositions and articles made therefrom
    Patent number: 3998917
    Abstract: This invention relates to slurry compositions which are adapted for the formation of ceramic articles. The compositions comprise ceramic particulate matter blended with an aqueous dispersion of an internally plasticized thermosetting resin. These compositions are formed into green (unfired) ceramic tapes which can be ultimately used for electronic purposes wherever fired rigid ceramic bodies are required. The use of these compositions overcomes many of the prior disadvantages relating to dimensional stability, flexibility, atmospheric stability and compatibility with a wide variety of conventional metallizing pastes.
    Type: Grant
    Filed: February 12, 1975
    Date of Patent: December 21, 1976
    Assignee: E. I. Du Pont de Nemours and Company
