Growth behavior of 211 particles in the Y‐Ba‐Cu‐O system was investigated using CuO and CuO + BaCuO melts. The inhibiting effect of Sn on the growth of 211 particles was not as great for the specimen heat‐treated using CuO + BaCuO melts. Fast growth of 211 particles was observed in the CuO melt at high temperature (1100°C), whereas the growth of 211 particles was extraordinally suppressed by the addition of Sn to the CuO melt. It is believed that Sn Is an effective element for the refinement of 211 particles in the Y‐Ba‐Cu‐O system but that additional Ba nullifies the refinement effect of the Sn.
