| Abstract: | The In-situ grown SiCw formate by adding some silicon and active carbon in Al2O3-C refractories. The grown mechanism of In-situ grown SiCw was studied by means of SEM and EMA. A new grown mechanism, L-S (Liquid-Solide ) mechanism, is advanced. The thermdynamic and dynamic conditions were also discussed. |
