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日本亚洲欧美日韩工程、hematite、 SFCA911影视免费看、larnitewww.十八岁A片、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.
