To gain deeper understanding concerning the stabilization of tetragonal ZrO2 nanoparticles when only monoclinic ZrO2 is expected, the critical size theory has been established many decades ago. However, the theory has not yet found a consensus in the scientific community. We herein propose a new synthesis method, based on non-hydrolytic sol-gel (N.H.S.G.) reactions performed in supercritical alcohols, to stabilize ZrO2 nanoparticles below the critical size limit generally admitted (< 3 nm). Conventional ex situ analysis techniques such as X-ray diffraction, Raman and Infrared spectroscopies and transmission electron microscopy were combined to investigate the crystal structure of ultrafine ZrO2 nanoparticles formed in supercritical continuo...
