  A process for the preparation of a titanate which comprises adding an aqueous solution containing ions of titanium and at least one metal selected from the group consisting of Ba, Ca, Sr, Zn, Cd and Pb to an aqueous alkaline solution containing hydrogen peroxide, recovering the resulting precipitate and heating the precipitate at a temperature not lower than 100.degree. C to give the titanate of the metal as used in uniformly fine particles. The resulting titanate can be used as ceramic materials for electronic elements.

  A side-by-side comparison of the TiO2 deposition kinetics and the corresponding microstructures was studied. The two precursors were titanium(IV) isopropoxide and anhydrous titanium(IV) nitrate, and all depositions were conducted at low pressures (<10(-4) Torr) in an ultrahigh vacuum chemical vapor deposition reactor. For both precursors deposition kinetics were qualitatively similar and exhibited three distinct regimes as a function of temperature. At the lowest temperatures, growth was limited by the rate of precursor reaction on the substrate surface. At intermediate temperatures flux-limited growth was obtained, and at the highest temperatures the growth rates decreased with increasing temperatures. The overall behavior was modeled quantitatively for each precursor using a two-step mechanism involving reversible adsorption followed by irreversible reaction. Titanium(IV) nitrate exhibited a lower activation energy of reaction (E-r = 98 kJ/mol) which allowed deposition at lower temperatures compared to titanium(IV) isopropoxide (E-r = 135 kJ/mol). The film microstructures were examined using transmission and scanning electron microscopy and X-ray diffraction. Comparison of the microstructures of films deposited at similar temperatures revealed significant differences in the reaction rate-limited regime. As the growth rates of the two precursors converged in the flux-limited regime, the respective microstructures became indistinguishable. The importance of precursor surface coverage and diffusion on this effect is described.
