Point defects in langatate crystals
Abstract Langatate crystals of the general composition $ La_{3} $($ Ga_{0.5} $$ Ta_{0.5} $)$ Ga_{5} $$ O_{14} $, grown by the Czochralski method, have been investigated by neutron diffraction (single crystals) and X-ray diffraction (ground single crystals). The crystals were grown in an atmosphere o...

| 520 | |a Abstract Langatate crystals of the general composition $ La_{3} $($ Ga_{0.5} $$ Ta_{0.5} $)$ Ga_{5} $$ O_{14} $, grown by the Czochralski method, have been investigated by neutron diffraction (single crystals) and X-ray diffraction (ground single crystals). The crystals were grown in an atmosphere of 99% Ar + 1% $ O_{2} $ in the Y54° direction (rotation by 54° with respect to the y axis), without subsequent annealing (orange crystal) or with vacuum annealing (colorless crystal). It is established that colorless crystals have a higher gallium content and, therefore, a larger number of oxygen vacancies in comparison with colored crystals; this is a possible reason for their lower microhardness. | ||

Point defects in langatate crystals |
| abstract |
Abstract Langatate crystals of the general composition $ La_{3} $($ Ga_{0.5} $$ Ta_{0.5} $)$ Ga_{5} $$ O_{14} $, grown by the Czochralski method, have been investigated by neutron diffraction (single crystals) and X-ray diffraction (ground single crystals). The crystals were grown in an atmosphere of 99% Ar + 1% $ O_{2} $ in the Y54° direction (rotation by 54° with respect to the y axis), without subsequent annealing (orange crystal) or with vacuum annealing (colorless crystal). It is established that colorless crystals have a higher gallium content and, therefore, a larger number of oxygen vacancies in comparison with colored crystals; this is a possible reason for their lower microhardness. © Pleiades Publishing, Ltd. 2009 |
