Ceramic dielectric porcelains
Abstract
Abstract PRODUCTION OF SINTERED CERAMIC PORCELAIN DIELECTRICS HAVING A PREDOMINANT SPINEL PHASE AND AIR SINTERED BETWEEN 800-900* C. FROM A GREEN SHEET PROVIDING UNIFORM DIELECTRIC PROPERTIES AND COMPRESSIBILITY FOR LAMINATION OF STACKED GREEN SHEETS INTO A UNITARY LAMINATE WHICH MAY BE PROVIDED WITH INTERNAL PATTERNS OF ELECTRICAL CONDUCTORS EXTENDING THEREIN. THE STRUCTURE IS OBTAINED BY BLENDING THE CERAMIC PARTICULATE WITH A SUITABLE GLASS AND LOW TEMPERATURE FIRING OR SINTERING THE COMPOSITION BETWEEN SAID 800-900* C. DENSIFICATION OF THE GREEN MODULE AND METALLIZATION, GLASS BEAD SELAING OF THE PINS, AND HARDENING OF THE PINS BY OXIDATION WERE ACCOMPLISHED IN A SINGLE AIR-COFIRING IN THE ABOVE TEMPERATURE RANGE.
