Ceramic Chemical Sensors An Overview

Coorstek center for advanced materials.

Ceramic chemical sensors an overview.

Coorstek sensors was formed to develop manufacture and deliver unique ceramic based smart sensors to help improve the environment around us combining the unique technologies of emisense emission sensors and pegasor air quality monitors for continuous real time on board and stationary monitoring. Some porous electrodes require two mode distributions of pore sizes. Potentiometric sensors make use of thermodynamic equilibration between the gas and the solid. Small pores are for the electro chemical reactions while large ones are for flow paths of reactants.

Many electrodes used in electro chemical devices including gas purifiers gas sensors fuel cells and chemical analyzers are porous ceramics. Chemical sensing principles methods and applications. The general bibliography on chemical sensing contains a more complete exposition this chapter develops a taxonomy for this broad sensor class describes some promising application areas e g the detection of toxic chemicals in the environment and highlights the key materials challenges. Sensor needs in the glass industry glass industry.

Electrostatic potential drops across interfaces caused by the exchange of ions together with electrons may be used in various ways to measure the concentration of chemical species.
