Abstract

Nanopowder of a new tin(II) titanium(IV) oxide hydroxide fluoride, Sn _1.24Ti_1.94O_3.66(OH)_1.50F _1.42. with the pyrochlore-type structure (cubic a = 10.3777(7) Å, space group Fd3̄m) was prepared at 180 °C and pH 2 by using a microwave assisted solvothermal reaction. The grain size of the nanopowder was 20-30 nm. It decomposed into a mixture of anatase-type and rutile-type Sn _0.39Ti_0.61O₂ at around 400 °C. A single phase of rutile-type Sn_0.39Ti_0.61O₂ (tetragonal a = 4.6805(6), c = 3.0961(4) Å, space group PA₂/ mnm) having a grain size of about 100 nm could be obtained by heating Sn _1.24Ti_1.94O_3.66(OH)_1.50F _1.42 at 800 °C.
