Crystallite size is closely related to CH/sub 4/ sensitivity for SnO/sub 2/ sensors. The crystallite size is growing during heat treatments such as calcinations and sintering. To develop highly sensitive methane gas sensors some dopants as crystallite growth inhibitors are added to SnO/sub 2/ powder. This paper is mainly concerned with effect of heat treatment of SnO/sub 2/ doped with various grain growth inhibitors on CH/sub 4/ sensitivity. We fabricated thick film methane gas sensors using… CONTINUE READING
