Paper Abstract

The new crystal KNB (KNbB2O6) has been discovered and the XYB2O6 family of isomorphs (where X equals Cs, Rb, K, Y equals Nb or Ta) has been identified as a potential structure for non-linear optical applications. KNB was grown using a resistance heated TSSG scheme in an excess of B2O3 and K2O. It was found that KNB has orthorhombic symmetry with space group Pna21, unit cell parameters a equals 31.236(4), b equals 7.315(2), c equals 9.210(4) angstroms, and is isostructural with RNB (RbNbB2O6), which was also grown. The non-linear properties of both members were assessed and discussions are presented on the origin of the non-linearity in this family of compounds.
