The phase diagram gadolinium fluoride-lutetium fluoride was determined by differential scanning calorimetry (DSC) and X-ray powder diffraction analysis. Both pure components undergo a reversible first order transformation to a high temperature phase. The mutual solubility of both components is unlimited in the orthorhombic room temperature phase. The maximum solubility of Lu in the high temperature phase of GdF{sub 3} (tysonite type) is about 20% and the maximum solubility of Gd in LuF{sub 3} ({alpha}-YF{sub 3} type) is about 40%. Intermediate compositions of the low temperature phase decompose upon heating in a peritectoid reaction to a mixture of both high temperature phases. - The phase diagram GdF{sub 3}-LuF{sub 3}, {alpha}, {beta} mean high-T phase or low-T phase, respectively.
