Three-dimensional prismatic growth of TiO2 film via stacked-layer ridge formation on 18 SWG Ti wire when heated at 1100C/2h in: static air ( 2Op =
0.21 atm.) left, and, a CO2/CO buffer mixture ( 2Op = 3.8 x 10-21
atm.) right. The systematic self-reconstitution and re-organization on the
microscopic level form leading to tightly-packed growth consisting of stacked-layers of consecutive triangular prismatic ridges, has been explained in
terms of a newly defined interfacial Gibbs' free energy criterion that must be satisfied thereby warranting the microstructural adjustment at each
stage of the growth process. The `stability' criterion is discussed in a new paper which appears in the July 2008 issue of International Journal of
Applied Ceramic Technology (doi: 10.1111/j.1744-7402.2008.02227.x).
