摘　　要：SiAlON较Si_3N_4具有更好的高温稳定性,在炼铁体系具有更好的实用性;MgAlON比AlON低温稳定性好,是洁净钢、精品钢等炼钢体系用耐火材料;Al_4O_4C和Al_2OC是树脂结合Al-Al_2O_3系耐火材料高温增强相,具有无铬、低碳环保特点,用于连铸功能耐火材料具有很好的使用效果。基于此,介绍了Si-N-O、Si-Al-O-N、Mg-Al-O-N和Al-Si-C-O-N系结合相复合材料等的应用研究现状,展望了其发展前景。Compared to Si3N4, SiAlON has a better stability at high temperatures, which can be used in steel-making. MgAiON as a kind of refractory for clean steel and steel of super quality has a better stability at low temperatures than AlON. Al4O4C and Al2OC with chrome-free and low carbon are strengthened phases in resin bonded Al-Al2O3 composite, which can be applied as continuous casting refractory. The review represented the phases in Si-Al-N-O system bonded composites, phases in Si-Al-C-N-O system bonded composites and phases in Al-S-C-O-N system bonded composites. In addition, the future developments were also proposed.
