Ta-Y (Tantalum-Yttrium) Editor The solubility of Ta in liquid Y (1526 to 2083 C) was measured by [66Den]. The solid solubility of Ta in (Y) is less than 0.1 at.% [61Lun]. According to the Van't Hoff relationship, the L = (bY) + (Ta) eutectic temperature is not more than 9 C below the melting point of bY. The solid solubility of Y in ( Ta) is less than 0.0001 at.% at 1585 C [65Tay]. There are no compounds in this system [66Den], and Ta and Y are immiscible in the liquid state [ 59Sav].-H.O. 59Sav: E.M. Savitskii and V.F. Terekhova, Tsvetn.
