Liquid phase Y(CHO2)326.371.599Y(CHO2)3•2H2O
 Notes:
   a  This value was calculated by the compiler.

 Method/Apparatus/Procedure:
   The isothermal method was used. Equilibrium was attained in two weeks. The yttrium content was determined by titration with Complexone III. The composition of the solid phases was determined by X-ray diffraction, by thermogravimetry and by IR spectroscopy.1

 Source and Purity of Materials:
   The yttrium formate dihydrate was prepared by the reaction of Y2O3 with dilute A.R. grade formic acid.1

 Estimated Errors:

   Temperature: The temperature was controlled to within ±0.1 °C.2
