Probing the structure of titanium silicates over a wide range of length scales

DOI

Titanium silicates are important for a number of applications such as ultra low expansion glasses, anti-reflective thin film coatings and catalytic materials. Titanium silicates xerogels also provide interesting and challenging samples to exploit fully the potential of NIMROD. SAXS data has shown inhomogeneities are present over a wide Q-range, e.g. for Q < 0.05 Å-1 there is a departure from Porod scattering indicating that particle surfaces are rough, and for 0.1 < Q < 0.4 Å-1 there is a plateau feature corresponding to micro-pores within the network. Phase separation can also be induced by either increasing the titanium concentration or by heat treating which creates volume elements containing substitutionally incorporated Ti and those rich in titania crystallise to anatase. This phase rich system is therefore an ideal system to exploit fully the potential of NIMROD.
