Abstract
- Single-phase LuGaTi<subscript>2</subscript>O<subscript>7</subscript> samples have been prepared by solid-state reaction in a starting mixture of Lu<subscript>2</subscript>O<subscript>3</subscript>, Ga<subscript>2</subscript>O<subscript>3</subscript>, and TiO<subscript>2</subscript> via sequential firing in air at temperatures of 1273 and 1573 K. The crystal structure of the lutetium gallium dititanate has been determined by the Rietveld method (profile analysis of X-ray diffraction patterns of polycrystalline powders): sp. gr. Pcnb; a = 9.75033(13) Å, b = 13.41425(17) Å, c = 7.29215(9) Å, V = 957.32(2) Å<superscript>3</superscript>, d = 6.28 g/cm<superscript>3</superscript>. The heat capacity of LuGaTi<subscript>2</subscript>O<subscript>7</subscript> has been determined as a function of temperature by differential scanning calorimetry in the range 320–1000 K. The C<subscript>p</subscript>(T) data thus obtained have been used to calculate the principal thermodynamic functions of the oxide compound. [ABSTRACT FROM AUTHOR]
