Different methods have been adopted for the preparation of phase pure Zirconia. The sol–gel route

In recent years, the growth of crystals in gel medium has attracted the attention of many investigators [ 1 – 5 ]. The principle of growth is based on the slow migration of crystal constituents (ions) through
