DTA confirms the formation of tetragonal to monoclinic zirconia takes place at higher temperature in the presence of silica. X-ray diffraction analysis indicates that the monoclinic content decreases with increase in silica content. FT-IR has been used to elucidate the presence of Si-O-Si network in silica-doped zirconia nanopowders. The TEM image indicates that the zirconia.nanoparticle size decreases with increase in silica content with a mean size of 15-40 nm. (c) 2008 Elsevier B.V All rights reserved.
