Crystal growth of NdAl3(BO3)4 from K2O/MoO3/Nd2O3/B2O3/KF flux

Abstract NdAl 3 (BO 3 ) 4 single crystals were grown by the flux method and the TSSG technique using a K 2 O/3MoO 3 /B 2 O 3 /0.5Nd 2 O 3 /KF flux system. Light-violet clear crystals could be obtained. The effects of fluoride on the growth of NAB crystals were investigated. As the content of KF was gradually increased, the growth form of NAB was changed from the equant to the columnar and the primary crystalline region of NAB was shrinked. At the ratio of KF K 2 O = 0.75 , NAB crystals could not be grown.
