氮化硅與碳化硅有著相似的化學(xué)結(jié)構(gòu)和物理性質(zhì)，與碳化硅均為強(qiáng)共價(jià)鍵化合物。氮化硅的熱膨脹系數(shù)小，氧化速度非常慢，高溫強(qiáng)度大，體積穩(wěn)定性好，有良好的導(dǎo)熱性，對(duì)于多數(shù)化學(xué)物質(zhì)都穩(wěn)定，不被熔融有色金屬所侵蝕，是碳化硅理想的結(jié)合材料。將氮化硅引入碳化硅內(nèi)制成氮化硅結(jié)合碳化硅材料，在保持了碳化硅固有特性的同時(shí)，可以有效地提高碳化硅材料的高溫強(qiáng)度、熱震穩(wěn)定性和抗鐵水侵蝕能力等性能，而且可以在1200-1450?的較低溫度下制備，反應(yīng)燒結(jié)過(guò)程為凈尺寸燒結(jié)，利于制備異形制品，適應(yīng)大規(guī)模工業(yè)生產(chǎn)。反應(yīng)燒結(jié)制備的氮化硅結(jié)合碳化硅耐火材料雖然已被應(yīng)用于鋼鐵、有色及建材工業(yè)，但隨著科技的進(jìn)步，現(xiàn)代工業(yè)的工藝技術(shù)不斷發(fā)展，耐火材料所需面對(duì)的工作環(huán)境越發(fā)苛刻，這就對(duì)原先使用的耐火的性能提出了更高的要求。氮化硅結(jié)合碳化硅耐火材料的生產(chǎn)現(xiàn)在還存在很多問(wèn)題，如，如何保證硅粉的氮化率、如何控制氮化硅晶相組成、如何防止流硅現(xiàn)象的發(fā)生以及如何進(jìn)一步提高制品強(qiáng)度。</p></p><br
