The results show that REEs oxide have little effect on the decomposition of carbonate and they improve the sinterability of the raw meal;they also promote the formation of alite and growth of clinker minerals,and have beneficial effect on the uniformity of crystal size and well-distributed minerals. But some REEs result in the corrosion of alite when they are excessive,which may influence the hydration reactivity of alite.When clinker is well sintered, REEs oxide and its tailing improve the strength of cement clinker, and have little effect on setting time of cement.

The good catalytic performances were obtained on those catalysts supported by SiO_2. With the increasing calcination temperature from 300℃to 700℃, Co_3O_4 particles augmented and sintered on the samples surface which contained 10 wt.% cobalt, the crystallite size of Co_3O_4 was aggrandized from 7.2 nm to 20.3 nm by inchmeal. On the other hand, the activation energy for the combustion reaction was increased linearly with the augment of average crystallite size of Co_3O_4, the TOF value on prepared catalyst was decreased with it. Thus, the catalytic combustion was a typical structure-sensitive reaction.

The performace of material was tested by DSC,XRD,SEM,EIS and charge-discharge cycles . The influences of various synthesized condition , sintering time and the amount of F were studied and correlative technics parameter to improve performance of material were optimized. DSC shows that three endotherimc peaks and one large exothermic peak are observed in the temperature range 150-400℃, which is because of the removal of water,the decomposition of the organic constituents and the formation of spinel. Only the citrate precursor is sintered at least 450℃, the crystallinity of spinel phase could be formed intactly.
