Summary: | <p>By the sol-gel method of autocombustionan initial oxide system was synthesized for a receipt a nanodispersed Yttrium Iron Garnet. It was set that forming of the monophase system Y<sub>3</sub>Fe<sub>5</sub>O<sub>12</sub>begins at temperatures above 973 К in static air atmosphere. The crystalquasichemical formulas for Y<sub>3</sub>Fe<sub>5</sub>O<sub>12</sub> are offered. Dependence of concentration of defects from a degree non-stoichiometry of oxygen is calculated. It was set that the formation of garnet structure needed oxygen atmosphere annealing. Partial pressure of oxygen determines the resulting structure defects.</p><p><strong>Keywords:</strong> yttrium iron garnet, sol-gel-autocombustion method, isothermal annealing, atmosphere, crystalquasichemical formulas, defects.</p> |
