Methods of transmission electron microscopy were used to reveal the possibilities of stabilization of cubic and tetragonal zirconium dioxide by structure refinement. With the help of statistical analysis of grain structure the interrelation was found between mean grain size and polymorphous composition. It was shown that ultradisperse structure powder (grain size of 20 nm) was the necessary condition for obtaining stable high temperature modification of zirconium dioxide.
