Nanofibrous zirconia was fabricated by calcination of electrospun zirconium oxychloride/polyethylene oxide (PEO) composite fibers with different mass fraction of the components. ZrO 2 nanofibers were characterized by scanning electron microscopy (SEM), nitrogen adsorption at 77 K, and X‐ray diffractometry (XRD). It was revealed that increase in ZrOCl 2 /PEO mass ratio above the threshold value significantly decreases tetragonal phase (t‐ZrO 2 ) content and increases monoclinic phase (m‐ZrO 2 ) content in final ceramic nanofibers. Distinct t‐ZrO 2 → m‐ZrO 2 transformation takes place when average ZrO 2 grain size approaches to 30 nm.
