Rare earth borates and aluminoborates single crystals were investigated for their applications as laser host materials and scintillators. The investigation of the ternary systcm Ln 2O 3-Al 2O 3-B 2O 3 (Ln = Gd) was undertaken in order to determine the thermal behavior, the best conditions of the growth from a melt and their ability to be reproduced. In first, the different solid phases formed in the binary system Gd 2O 3-B 2O 3 were studied and then the crystallization field of each phase was defined as a function of composition and temperature.
