Ir-Y (Iridium-Yttrium) H. Okamoto The Ir-Y phase diagram drawn by [Moffatt] was based on an assumed similarity to the Ir-La and Ir-Ce systems. In addition to the terminal phases, the existence of seven intermediate phases has been reported in this system. According to [89Bla], Ir3Y5 is found in four polymorphic forms. However, the phase relationships among them are unknown, except for the fact that the Mn5Si3 type is a high-temperature modification. 59Com: V.B. Compton and B.T.
