Antioxidation Characteristics of Surface-Modified Carbon in ${Al_2}{O_3}$-C Refractory

ABSTRACT

Antioxidation characteristics of carbon at high temperature with the co-addition of Al and Si powder in Al2O3-C system refractory were analyzed. The use of surface-modified phosphate carbon as a starting material was found to be very effective in improving the mixing effect of raw materials and antioxidation behavior of carbon. In particular, this effect was dominant at higher temperatures than 130$0^{circ}C$.

Key words: Antioxidation, ${Al_2}{O_3}$-C, Refratory, Surface-modified phosphate carbon
