机械工程 刚玉 For example, the refractory product of SiAlON bonded corundum is used for blast furnace and so on. But As high cost of non-oxide products and the poor basic theory study about it as refractory, the non-oxides refractory application is limited. 从目前的研究看，非氧化物在耐火材料中的应用非常成功，如Sialon结合刚玉制品作为高炉陶瓷材料等，但是由于非氧化物的生产成本高以及非氧化物及其复合材料用作耐火材料的基础理论研究还不够，限制了非氧化物在耐火材料中的应用和转化。 刚玉石
