| 摘 要： | 采用Ｘ射线衍射（ＸＲＤ），差热分析（ＤＴＡ），扫描电镜（ＳＥＭ）和红外光谱（ＩＲ）等手段研究了ＴｉＯ２和ＺｒＯ２对Ｂ２Ｏ３－ＭｇＯ－ＳｉＯ２渣中含硼组分晶化行为的影响，结果表明，ＴｉＯ２和ＺｒＯ２作为晶核剂加入后，促进分相，降低了晶化活化能，有利于含硼组分以２ＭｇＯ．Ｂ２Ｏ３和３ＭｇＯ．Ｂ２Ｏ３，析出，加入ＴｉＯ２改变了硼渣结构，产生更多有利于２ＭｇＯ．Ｂ２Ｏ３和３ＭｇＯ．Ｂ２Ｏ３析出的（Ｂ２Ｏ５

| Abstract: | The crystallization behaviors of the boron component bearing B2O3-MgO-SiO2 slag with TiO2 and ZrO2 as nucleation agents ulere investigated by Xray diffraction (XRD), differential thermal analysis (DTA), scanning electron microscopy (SEM) and infrared ray(IR) spectrum. The results showed that TiO2 and ZrO2 decreased the activation energy of crystallization and improved the phase separation, thus make the crystalline phase 2MgO.B2O3 and 3MgO.B2O3 precipitate easily.Meanwhile, the Structure of slag was modified by addition of TiO2 and a lot of B2O5] and BO3] which were favorable to make the crystals of 2MgO.B2O3 and 3MgO.B2O3 precipitate were produced. |
