Is there a precise definition of refractory metals? The titanium article includes titanium among the refractory metals.

Our Mission: Includes all technical aspects of the science of refractory metals and materials which are defined as those having melting points in excess of 1850K, with the exception of titanium.

Creep section[edit]

I was reading the creep section, and found it particularly bad. A recap of the definition of creep would be nice, as well as how all those applications and tidbits are related to creep. Someone who knows what they are doing should rewrite/reorganize that whole section. I merely added a link to creep. Drxenocide (talk) 20:43, 14 January 2011 (UTC)

Chemistry topics[edit]

If this could be promoted to GA, we'd have another chemistry good/featured topic! Lanthanum-138 (talk) 02:39, 9 May 2011 (UTC)

Why no Os?[edit]

Is there a reason Osmium is excluded from this group in most definitions? Its melting point is 3306K, higher than those of Nb, Ta, and Mo, and exceeded only by W and Re. Does it have anything to do with osmium tetroxide being volatile (and therefore unsafe)? Difluoroethene (talk) 18:59, 18 September 2011 (UTC)

Some authors include it, but I imagine this is a significant issue with Os, since the reaction to form OsO4 happens gradually at ambient temperature: that's how it got its name, after all! Also, if Ti makes the cut, then so should Pt with a melting point of 2041 K. I can understand Th (melting point 2115 K) being snubbed for its radioactivity, but we're not even consistent with our 2123 K criterion (which would list Zr, Cr, V, Rh, [Tc], Hf, Ru, Ir, Nb, Mo, Ta, Os, Re, and W, but not Ti). (For the 2000 °C list, start at [Tc]; for the 2200 °C list, start at Hf.) Double sharp (talk) 16:57, 18 June 2016 (UTC)
