[QUOTE="338Shooter, post: 1221385, member: 3449"] Look up Titanium Sublimation Pump. Clean titanium is very reactive, it forms an oxide layer almost instantly in the presence of O2. This oxide layer (passivation) is why it is so nonreactive in the form we use it in. Clean titanium probably has a very similar reactivity of clean aluminum which is also another big beneficiary of passivation. TSPs are used in ultra high vacuums which are used in molecular beam epitaxy. Oh, also, the titanium you etched was likely a Ti alloy with some combination of one or more of Al, V, Pd, Fe, Mo, Cr, and Sn. Likely you dealt with Grade 5 or Grade 9 Ti alloy. [/QUOTE]
