Synthesis of 6‐nm Ultrafine Monoclinic Zirconia

Abstract

In the normal paradigm of sintering‐densification, grain growth, creep, etc., it is anticipated that, at extremely fine grain size, various phenomena will be exaggerated so as to make direct observation more tractable; this gives impetus to attempts to synthesize such fine‐grained materials. In the present case, 6‐nm monoclinic zirconia was produced by a hydrothermal technique and is showing very interesting grain growth and rearrangement effects in transmission electron microscopy.
