| Abstract: | The chemical reactions in Si-C-O complex system and the passive oxidation and active oxidation in silicon carbide products are analyzed from thermodynamics.The areas of condensed phases stability in Si-C-O system are drawn under the condition of existing surplus carbon.The calculation results show that there is some amount of SiO gas in gas phase and that has created a condition for forming silica fume. |
