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

Curved growth lines are a prominent feature of virtually all Verneuil synthetic corundums. - 2
Due to stress in the growth process, a parting plane forms in all Verneuil grown synthetic corundums. 由于生长过程中产生的应力，所有维尔纳叶合成刚玉都会有这样的分割面。 - 3
The corundums, coated with a special resin, are sawn by thin diamond - polished blades. the discs are then separated, cleaned and sorted. 用极薄的金刚砂抛光锯片，将外涂特殊树脂的金刚石切成若干圆片，然后将圆片分离、洗净并分类。
