Book Description
The first book to present a
detailed analysis of the electrochemistry, development, modeling,
optimization, testing, and technology behind modern zirconia-based
sensors, Electrochemistry of Zirconia Gas Sensors explores
how to tailor these sensors to meet specific industrial needs. The book
addresses a range of different stages of development in zirconia-based
sensors for gaseous and molten metal environments, focusing on an
accessible form from analysis of interaction at the measuring
environment-zirconia sensor interface to reliability testing of the
sensors.
The book highlights different fundamental aspects of electrochemistry
and physical chemistry of zirconia, mathematical modeling, optimization
parameters, and structures of the electrode materials. The author
details the factors that determine high sensitivity, critically reviews
the limitations of current technologies, and surveys the needs and
possibilities of future developments. He covers technologies for
vacuum-tight joining zirconia to ceramic insulators and sensor
construction materials as well as sensor design and concepts of the
total-NOx sensor based on mixed potential. The book also includes a
critical overview of existing technologies of zirconia gas sensors
including nanotechnology.
This book fills the gap
between pure academic research of the zirconia-based gas sensors,
explaining the influence of the double electrical layer on the sensor
output signal and the applied, technological, down-to-earth approaches
adopted by the vast majority of the industrial companies working in this
field. Providing guidance on how to organize a testing program of gas
sensors, the book allows readers to look forward in evaluating future
trends in the zirconia gas sensors development.
