不同处理方式对镁渣理化特性的影响

Abstract

Abstract: A lot of magnesium slag（MS） is produced in the production of metallic magnesium by Pidgeon′s reduction method， and the random dispose of magnesium slag caused serious environmental problems.The physico-chemical properties of magnesium slag have a big effect on its comprehensive utilization.The influences of three treatment methods，such as natural cooling，air cooling，and water quenching on physico-chemical properties of MS after furnacing，were studied by BET，XRF，FTIR，XRD，and SEM. The results indicated that MS was a kind of alkali slag; the different cooling methods can lead to great different in the physico-chemical properties，such as particle distribution，pore distribution，mineral composition，and micro morphology of treated slags；The bigger particle，pore size，and specific surface area，the lower content of γ-C2S and the higher content of β-C2S could be obtained for the higher cooling rate.

Key words: magnesium slags, cooling methods, physico-chemical properties
