A transition layer paste is designed and fabricated for solving zirconia oxygen sensor technology in the process of heterogeneous material sintering matching problem

transition layer pulp as the " glue" to make different material co-firing union

improve the bonding strength between the layers of sensor and avoided due to the material shrinkage stress caused by inconsistent heater interlayer defects such as crack

air chamber airtight is lax. The oxygen sensor adopts the HTCC process technology

and is made through the processes of flow casting

punching

printing

lamination

slicing

gluing and sintering. The sensor is characterized by short response time and long service life. The zirconia oxygen sensor designed and manufactured in this paper based on the transition layer material has been tested

and its response time is shortened from 30 ms to 11 ms

and the upper output value is promoted from 280 m V to 800 m V.
