Titanium Dioxide Reactivity

  1. Aug 29, 2009 #1
    I've thought of titanium dioxide as a very inert material--until yesterday when I was reading its MSDS and found out it shouldn't be combined with strong acids or oxidizers. Why? Is this at room temperature or several hundred °C?

    Not combining it with reactive metals makes sense to me--it's an oxygen donor at elevated temperatures, but at room temperature it's nonreactive.

    Oh, I think I might have my answer now: it's functioning as a catalyst in reactions involving oxidizers and/or acids; it's not chemically altered itself by them.
