Title: Electronically conducting ceramic electron conductor material and the process for producing an air-tight seal in an oxygen sensor with an internal reference

Patent ·
OSTI ID:1531730
; ; ;

A method and an article of an electrically conductive ceramic interconnect bonded to a compatible ceramic housing for an oxygen partial pressure sensor system. The interconnect includes a LaxSryAlzMn1−zO3 (LSAM) having a stoichiometry enabling good electrical conductivity at high temperatures and the LSAM also bonded to a yttria stabilized zirconia forming a stable and durable seal.
