摘 要: 应用差热分析（DTA）技术研究了Cr2O3、 La2O3、 CeO2、 V2O5、 Si3N4、 SiC、 CaF2、 MOx对MgO-B2O3-SiO2渣中含硼组分析晶活化能的影响。结果表明, Cr2O3、CeO2、 CaF2、 SiC、 MOx作为晶核剂加入后, 可降低析晶活化能,有利于含硼组分以结晶相析出, 是有效的晶核剂； La2O3和V2O5对析晶活化能没有影响；V2O5则增强玻璃网络稳定性, 提高析晶活化能。 所以La2O3、V2O5和Si3N4作为晶核剂是无效的.

Abstract:The crystallization kinetics of the boron component bearing MgO-B2O3-SiO2 slag with Cr2O3 , La2O3, CeO2, V2O5, Si3N4, SiC, CaF2, MOx as nucleation agents were studied using differential thermal analysis(DTA). The results showed that Cr2O3, CeO2, SiC, CaF2, MOx decrease the activation energy of crystallization, that make the crystalline phase precipitate easily. However, the activation energy of crystallization is increased by addition of Si3N4, the effect of La2O3 and V2O5 on the activation energy of crystallization is little.
Key words: slag containing boron nucleation agent activation energy of crystallization
