| ABSTRACT |
|
Al2O3-SiC-C(ASC) refractory materials were prepared from kaolin using thermit reaction. The mixed powder (A-K) for the thermit reaction was composed of Hadong kaolin, C(graphite) and Al. A-S(SiO2＋C＋Al) composition was also employed to compare with A-K in respect to reactability. As a result of XRD patterns of A-K sample after thermit reaction, and firing at 140$0^{circ}C$ for 3hrs in Ar atmosphere, it was possible to use as a ASC refractory materials. |
