SiO2/SnO2 = 80/20 gel samples are prepared from Si(OEt)4 and SnC14 or Sn(OEt)4. Samples doped with Sb oxide contents up to 4% are also studied. The evolution of these samples after treatment from room temperature to 1050Β°C is studied by n9sn Mrssbauer spectroscopy and X-ray analysis. Results indica
