<p>107C-142 The present invention relates to a method for rapidly determining the insulation resistance characteristics of bismuth-containing ceramic capacitors, and more particularly to ceramic capacitors incorporating a barium titanate dielectric. The test is predicated upon the discovery that capacitors of the type described and having satisfactory insulation characteristics exhibit a high percentage of inter-granualar fracture. Capacitors of identical composition and apparently identical physical characteristics which when fractured, evince a high percentage of trans-granular fractures have been found to exhibit unacceptably low insulation resistance characteristics.</p> |
