Abstract |
In the process of studying the mechanisms of influence of structural defects on properties in scandium oxide, the thermal and electrical effects in the temperature range 25 – 1800 C in a vacuum, in the struc-ture was of detected a gradual phase transition of the ordered cubic type C in a disordered type C1 in the temperature range of 400 – 1000 C. Phase transformation is accompanied by the difference of the conduc-tivity type of the charge carriers. Anion conductivity of charges in the structure of scandium oxide exist there is to 400 С, with the energy of conductivity charges 2.46 eV. In scandium oxide in the interval tem-peratures 400 – 1000 C in case there is a mixture of two types of conductivity anion and electronic. In the interval of temperatures 1600 – 1800 C in case there is a change of the chemical composition of the oxide on the content of oxygen. With the help of the mathematical model of calculation of the elements of the structure of the change in the size of the radii of oxygen and anionic vacancies, which coincides with the change of parameters of elementary cells in the transition of the structure of C in C1.
