Abstract

In the field of gas sensors and high temperature flow sensors, ceramic thick-film-based structures play a key role, particularly in harsh environments. Their substrates have to be electrically insulating and chemically inert. Ceramic substrates, especially alumina ones, are often considered as ideal sensor substrates. However, neither their electrical resistivity nor their chemical inertness is ideal. Even the thermal conductivity is that temperature dependent that one has to consider it when modeling temperature profiles. In this contribution, measurements on the resistivity and the thermal conductivity between room temperature and 800°C of two related materials used for gas sensors substrates – alumina and LTCC ceramics – are presented. Additionally, resistance data of uncoated interdigital structures when exposed to NO₂ at around 300°C indicate that reactions between substrate and NO₂ may occur and have to be kept in mind.
