In this context "pure" is meaningless (truly 100% pure silicon is impossible to obtain in quantity), whereas "ultra pure" is a technical term that refers to a specific level of purity. The meanings are context dependent. It isn't haphazard, it's actually hyper specific and the terms have clear definitions in context. And in this case they are defined in the article. |
