The limits of neodymium substitution for yttrium in (Y, Nd)Al 3 (BO 3 ) 4 crystals in preparation from solutions in molten potassium trimolybdate have been studied. The maximum neodymium concentration in the crystals was 72 at.%, this corresponding to the ratio Nd:Y = 1 in the solution. When this ratio exceeds unity, only potassium‐neodymium molybdate is formed. The distribution coefficient for neodymium is greater than unity and decreases both with the increasing Nd/Y ratio in the melt and with decreasing growth rate of the crystals. The unit cell parameters change in the series YAl 3 (BO 3 ) 4 NdAl 3 (BO 3 ) 4 in a non‐steady manner, this indicating that the structure is inclined to disordering.
