Abstract

A new perovskite was recovered from the high pressure-high temperature treatment of the cc-TiSbO3 form of N-4SnTeOj at 7 GPa and 950 °C for 30 minutes. Synchrotron x-ray powder diffraction data show the space group is P2Jn with o=5.40361(5), 6=5.46152(5), c=7.69288(7)A and β=90.034(3)°. Using disk samples of both polymorphs, the dielectric properties were mea' sured as a function of temperature. At ambient conditions, the perovskite form has a more than 1.5 fold enhancement in dielectric constant compared to the cx-TlSb03 form while the molar volume I and the molecular polarizability decrease. r °1999 Materials Research Society.
