What is the surface area of a single UO3 molecule? Should I use the diameters in Image:Uranium-trioxide-3D-vdW.png or Image:UO3.jpg? LossIsNotMore 05:12, 6 December 2006 (UTC)
I think you should first read up on collision theory or perhaps buy a book on chemical kinetics. The method you linked to at chemcomp.com is more relevant to proteins and the like, in liquid and solid phases. Also, what do you mean by the term condensation profile? Read van der Waals radius, too. You may want to ask for advice at Wikipedia:WikiProject Chemistry, as condensation kinetics may, I fear, be a rather complex phenomenon.

In Carter, R.F. and K. Stewart (1970) "On the oxide fume formed by the combustion of plutonium and uranium" Inhaled Particles 2:819-38 ( PMID 5527739) in particular, section (f) on page 836 indicates that about half of burning uranium goes into a gaseous vapor fume, instead of the aerosol particulates which have thus far been the only portion measured by those responsible for insuring depleted uranium munitions safety. Volatility of uranium trioxide (a/k/a uranyl oxide) gas can be plotted from Alexander (2005) and Ackermann et al. (1956), resulting in a very large DOF-adjusted R^2 corresponding to the 95% confidence interval shown. For the burning temperature of the shower-of-sparks which is the result of DU munitions use on hard targets, please see Mouradian and Baker (1963), and in particular figures 4 and 6 on page 392.
Would someone include the relevant portions of that, please? James S. 15:45, 24 January 2007 (UTC)

Depleted uranium is mentioned in the titles of three of the references, yet this substance is not mentioned even once in the actual text of the article. Why is this? Badagnani ( talk) 08:19, 31 July 2008 (UTC)
I did a search at random about this topic, and found the article In vitro chemical and cellular tests applied to uranium trioxide with different hydration states from the journal Environmental Health Perspectives. I don't see it in the list of references supplied with the article, and I haven't read it to ascertain its value. (Moreover, I'm not familiar with the journal, so I can't assess its value either.) I just thought I'd post this in the event there's something useful to be gleaned from it. Mind matrix 18:22, 9 November 2008 (UTC)
Based on electron densities, isn't this rendering more accurate than the ball-and-stick model in the article now? 99.191.75.124 ( talk) 08:10, 28 February 2010 (UTC)
We see formulae like UO2−
4 and U
2O2−
7 being thrown around here (presumably in analogy to Cr), despite the fact that the
uranate article notes that no actual uranium oxyanions are known and that all uranates are ternary oxides.
