Zirconium dioxide is of interest in connection with its possible use as a basis for materials for heat-resistant protective coatings. The authors study the phase composition and structural features of zirconium dioxide condensates obtained by the method of electron-beam evaporation and vacuum condensation onto a heated substrate. The specimens for the studies were obtained on a UE-109 apparatus by means of evaporation of ultrapure zirconium dioxide in a vacuum of 10/sup -3/ Pa. The vapor phase was condensed on polycrystalline molybdenum substrates. X-ray studies of the evaporated specimens were carried out. A second characteristic structural zone appears in zirconium dioxide vacuum condensates in the substrate temperature range 550-1000 C. A change in the nature of the preferred crystallite orientation appears at the substrate temperature 825 C. A third structural zone is observed in the condensates when the substrate temperature lies in the range 1100-1300 C. The transition from the second to the third structural zone occurs smoothly in the substrate temperature range 1000-1100 C.
