Melting and crystallization behavior of a high-T, compound Ba2YCu30, was investigated by microstructural observation, and compositional, thermal and X-ray analyses. Because of an incongruent melting, Ba2YCu30, decomposes into a solid phase, BaY2Cu0, and a liquid at 1266 K in air. Ba, YCu30, crystals are formed around the primary crystals, BaY2Cu0,, by a peritectic reaction on cooling from 1473 K in air.
