Abstract

Sintering of bulk YBa₂Cu₃O_x (123) samples has been conducted from 850 to 1010°C for various times in oxygen partial pressures (pO₂) of 2.5×10² to 10⁵ Pa. The final grain sizes of the samples were controlled by selective use of (a) liquid phases and (b) partial decomposition of the 123 phase by sintering in a pO₂ lower than the minimum needed for 123 stability. In nearly fully dense samples, it was found that the grain size could range from about 1 to 500 μm, depending on the processing conditions.
