摘 要：<正>A new niobate Sr6Ti7Nb9O42 was synthesized for the first time by solid state reaction in SrO-TiO2Nb2O5 ternary system. The new compound was characterized by EPMA, XRD, SEM and DTA. The X-ray owder diffraction data of Sr6Ti7Nb9O42 were firstly reported in the paper. Sr6Ti7Nb9O42 crystallizes the hexagonal system with unit cell parameters a=8.9991（4）（?）, c=11.5118（9）（?）, and space group P63/mcm（193）, z=1. The calculated and measured densities are 4.783 g/cm3 and 4.764 g/cm3, respectively.
