This thesis has systematically studies the microstructure of the sinter bearing fluorine of different compositions and in different sintering condition.(1) The main units of the Low Fluorine Sinter are magnetite、hematite、 SFCA、larnite、glass and pore. The cuspidine doesn't form for the low content fluorine, and the fluorine is in glass; Sinter basicity dominates the forming of the larnite and SFCA, when basicity is between 1. 72 and 1. 96, there are more larnites in the binder phase, and when the basicity is biger than 1. 96, there are more SFCA in the binder phase; the hematite appears like magnetite and usually is around pore.

It has been found that the cation exchange on diffusivity may play the role in different ways for different zeolites. When the diameter of the diffusant molecule is much smaller than the pore or cage size of the zeolite, the influence of exchanged cations is mainly by way of altering the electric field intensity (or the density of electric charge), the large the Z/r of the exchanged cations, the smaller the diffusivity; while the diameter of the molecule is apporsi- mately equal to the pore or channel size of the zeolite, the exchanged cations may affect the diffusivity by means of blocking up or narrowing the channels of the zeolite.

金属阳离子交换对扩散的影响表现为：当扩散分子的直径比分子筛孔道直径小得多时，交换阳离子以改变分子筛内部电场强度或电荷密度的方式影响扩散速度，阳离子的Z/r越大，扩散系数越小；当扩散分子直径与分子筛孔道直径相近时，交换阳离子则因堵塞或窄化孔道而改变分子的扩散速度。
