Formation of Porous Silicon Carbide and Its Suitability as a Chemical and Temperature Detector

Anodically etched PSiC films are then investigated for their suitability as chemical and temperature detectors. PSiC layers were unresponsive in interferometry for a wide variety of adsorbate gases, and this method of analyte detection proved unsuccessful. Conductometric investigations show that PSiC has a measurable response to high concentrations of hydrogen gas (∼6% decrease in resistance when exposed to 20% H2) comparable to currently used platinum alloy resistive films. Current hydrogen sensing arrays may be improved by the introduction of a PSiC sensor for the specific role of high concentration sensing.
