摘要
采用 L EITZ偏光岩相显微镜结合扫描电子显微镜 ,研究了实验室自制渣和工业结晶器保护渣的结晶矿相。结果表明 :在本实验中 ,渣样的结晶矿相主要有枪晶石、黄长石和硅灰石 ,个别渣样中可能有霞石析出 ;保护渣中加入少量的 Mg O可以降低结晶率 ,抑制硅灰石的生成 ;加入少量的 Mn O、Zr O2 可促进硅灰石的析出 。
The crystalline phases of laboratory prepared slags and commercial mold fluxes were studied by using LEITZ optical microscope and SEM The results show that:①Under the experiment conditions,the cuspidine,gehlenite and wollastonite are observed,and nepheline may exist in some slag samples;②With some MgO,the crystallization rate is lowered,and the form of wollastonite is restrained;③With small amount content of MnO,ZrO 2,the form of wollastonite is promoted,and the growth of cuspidine is restrained
