Total reflection x-ray fluorescence (TRXF) has been commonly used as an inline analytical tool to analyze metallic impurities on the Si … Witryna26 lis 2024 · Oxidation of silicon. Silicon's surface has a high affinity for oxygen and thus an oxide layer rapidly forms upon exposure to the atmosphere. The chemical reactions which describe this formation are: (7.11.1) Si (s) + O 2 (g) → SiO 2 (s) (7.11.2) Si (s) + 2 H 2 O (g) → SiO 2 (s) + 2 H 2 (g) In the first reaction a dry process is utilized ...
