Abstract
The solid-liquid equilibrium diagram of the system B{sub 2}O{sub 3}-Li{sub 2}O-H{sub 2}O is, up to now, known only in the temperature range 25 to 100 deg C. We determined the solubility isotherm in the system B{sub 2}O{sub 3}-Li{sub 2}O-H{sub 2}O at 300 deg C for B{sub 2}O{sub 3}/Li{sub 2}O mole ratio from 1 to 600 in solution. The values of saturation concentrations make it possible to predict the behaviour of a possible leak between primary and secondary circuit of nuclear reactors: the results show that at the beginning of the cycle, when the ratio B{sub 2}O{sub 3}/Li{sub 2}O is high, borate precipitation induced by boiling through the leak may lead to occlusion, and that this borate may dissolve when the ratio B{sub 2}O{sub 3}/Li{sub 2}O decreases during the course of the cycle. The solid phases identified by X-Ray diffraction were B{sub 2}O{sub 3}, Li{sub 2}B{sub 10}O{sub 16}H{sub 2}O, Li{sub 4}B{sub 10}O{sub 17}, Li{sub 2}B{sub 4}O{sub 7}, Li{sub 3}B{sub 5}O{sub 8}(OH){sub 2}, LiBO{sub 2}. The existence of Li{sub 3}B{sub 5}O{sub 8}(OH){sub 2} was not reported in low temperatures equilibrium systems.
