| Description |
Hexaferrites are well known for their important magnetic and data storage applications. The volatileorganic compound (VOC) sensing of hexaferrites is not reported yet in open literature. In the present work,acetone and ethanol sensing characteristics of nano-crystalline barium hexaferrite particles has beeninvestigated. The phase formation behaviour and microstructure evolution of the synthesized bariumhexaferrite particles are studied using X-ray diffraction (XRD) and high resolution transmission electronmicroscopy (HRTEM) techniques. Ultraviolet–visible (UV–vis) absorption and current–voltage studiesare carried out to confirm the semiconducting nature of the particles. Gas sensing study revealed bariumhexaferrite as promising sensor for the fast and reproducible detection of acetone and ethanol vapours atlow concentrations (20 ppm). The present systematic study on the promising acetone and ethanol sensingcharacteristics of barium hexaferrite particles could play significant role to explore the possibilities ofnon-conventional hexagonal ferrite sensors.
