Nanopowder of a new tin(II) titanium(IV) oxide hydroxide fluoride, Sn1.24Ti1.94O3.66(OH)1.50F1.42 with the pyrochlore-type structure (cubic a = 10.3777(7) Å, space group Fd-3m) was prepared by using a microwave-assisted solvothermal reaction. The grain size of the nanopowder was 20-30 nm in diameter. Sn1.24Ti1.94O3.66(OH)1.50F1.42 decomposed above 300 °C, but could be sintered to relative density greater than 99% by a hydrothermal hot-pressing (HHP) method at 270 °C and 80 MPa for 4 h. The synthesized powder and solidified body obtained using HHP showed significantly different color, probably due to the difference in water content.
