摘要
通过对低氟烧结矿显微结构的分析研究发现：微气孔直接控制着烧结矿裂纹的产生和扩展，并对烧结矿的强度有影响。低氟烧结矿中的微气孔是在铁酸钙（ＳＦＣＡ）结晶之后及玻璃体凝固之前形成的。低氟烧结矿中存在大量微气孔是由于其粘结相的熔点和结晶能力低造成的。因此提高低氟烧结矿粘结相的熔点及结晶能力是降低微气孔率、提高强度的根本途径。
The study on the microstructure of the sinter with low fluorine shows that there is a strong relation among the pores in the sinter, the forming and extension of cracks and the sinter strength. The pores form between SFCA crystallization and glass solidification. There are many pores in the sinter, which is attributed to low melting point and crystallization capacity of the binding phase. The basic way to decrease the pore number and improve the strength of the sinter with low fluorine is increasing the melting point and crystallization capacity of the binding phase.
