Abstracts

EN

The growth rate of Y_1Ba_2Cu_3O_{x} bulk single grain (in fact single crystal) superconductors in the system with composition Y_{1.5}Ba_2Cu_3O_{x} and CeO_2 addition was studied in the temperature range 991-1001°C. It is shown that the growth rate of bulk crystal is different for a- and c-growth direction. Slower measured growth rate in studied system than in pure Y_1Ba_2Cu_3O_{x} is related to the composition shift to the three-phase field containing CuO.
