tantalum pentoxide = triuranium octoxide edit
The image File:Kristallstruktur Triuranoctoxid.png featured in this article shows U3O8 – why the hell then is it in the article decsribing Ta2O5? Vinne2 (talk) 11:12, 1 June 2011 (UTC)

What is the refractive index? edit
The article says it is used because of its refractive index, but nowhere mentions what that might be? — Preceding unsigned comment added by 67.183.221.118 (talk) 17:20, 3 April 2012 (UTC)

Refractive index edit
Wikipedia says 2.275, but from https://refractiveindex.info/?shelf=main&book=Ta2O5&page=Bright-amorphous it seems that it is much higher, around 4 --132.66.39.177 (talk) 09:27, 17 July 2018 (UTC)
- Your ref says n = 2.1306 which is pretty close to what we have. You seem to be looking at the value for relative permittivity, which is a very different property. --Project Osprey (talk) 09:36, 17 July 2018 (UTC)
