摘要：
The pseudo-binary phase diagram between Y0.5Nd0.5Ba2Cu3Ox and Ba3Cu10O13 has been in-situ observed using high-temperature optical microscopy. It has been observed that the liquidus line is very narrow both in composition and temperature, which suggested that Y0.5Nd0.5Ba2Cu3Ox, crystals could only be grown from a peritectic melt consisting of (Y0.5Nd0.5)(2)BaCuO5 and a liquid. The crystal growth of Y0.5Nd0.5Ba2Cu3Ox was performed in a tubular furnace under a horizontal temperature gradient using alumina crucibles. Well faceted Y0.5Nd0.5Ba2Cu3Ox crystals up to a size of 7.3 x 5.8 x 1.28 mm(3) were grown.
