Crystalline bulk silicon is rather inert, but becomes more reactive at high temperatures. Like its neighbour aluminium, silicon forms a thin, continuous surface layer of silicon dioxide (SiO 2) that protects the metal from oxidation. Thus silicon does not measurably react with the air below 900 °C, but formation of the vitreous dioxide rapidly increases between 950 °C and 1160 °C and when 1400 °C is reached, atmospheric nitrogen also reacts to give the nitrides SiN and Si 3N 4. Silicon r… WebJul 20, 2024 · Maybe it is due to the fact that reaction ( 1) proceeds in two steps, with the intermediate formation of H X 2 S i F X 6. Maybe ( 1) proceeds like that. S i O X 2 + 6 H F H X 2 S i F X 6 + 2 H X 2 O. H X 2 S i F X 6 ↽ − − ⇀ S i F X 4 ( g) + 2 H F. H X 2 S i F X 6 is well known to be formed if H F is in excess.
