Phase diagrams were constructed for YCl/sub 3/ - NaCl and YCl/sub 3/-- KCl systems. The melting points of yttrium, sodium, and potassium were 700, 800, and 774 deg , respectively. A thermal analysis revealed a white chemical compound Na/sub 3/YCl/sub 6/ with a melting point of 550 deg . The Na/sub 3/YCl/ sub 6/ formed a eutectic with yttrium chloride containlng 45 mole% NaCl and melting at 360 deg . A thermal analysis of the YCl/sub 3/-KCl system revealed two chemical compounds: white colored KY/sub 3/Cl/sub 10/ and K/sub 3/YCl/sub 6/ melting congruently at 535 and 830 deg , respectively. The eutectic formed by KY/ sub 3/Cl/sub 10/ and K/sub 3/YCl/sub 6/ contained 50 mole% KCl and melted at 430 deg , and the eutectic of K/sub 3/YCl/sub 6/ with KCl contained 87 mole % KCl and melted at 675 deg C.
