高炉用氮化硅结合碳化硅制品化学分析方法的研究

Chemical analysis on Si_3N_4bonded SiC products for blast furnace

确定了高氧化铝含量（０．５％－２０％）的高炉用氮化硅结合碳化硅制品中Ｓｉ３Ｎ４、ＳｉＣ、ｆＳｉ、ＳｉＯ２、Ｆｅ２Ｏ３、Ａｌ２Ｏ３六种化学成分的化学分析方法试验条件．并按条件试验选择了分析方法，进行了精密度、准确度和实际工作的考核，证明了本分析方法可靠、切实可行，能满足科研工作和生产的要求。

A chemical analysis has been posed for the determination of Si3N4,SiC,fSi,SiO2,Fe2O3,Al2O3in the Si3N4 bonded Sicproducts containing higher alumina content(0.5%-20% ). The practice has justified its accuracy and precision and reliability.
