In this paper,the phase relation of system Al_2O_3-B_2O_3-Nd_2O_3at room temperature have been reported by X-Ray and DTA analyses.There isjust one ternary compound NdAl_3(BO_3),(abbreviated as NAB) in,this system.The compound has a phase transition at 95±15℃.The high-temperature formof NAB has a SHG efficient of KDP order of magnitude and the low-tempera-ture form of NAB has no SHG efficient.
