The deliquescence of high activity Mg O was studied by fluidized bed reactor at normal temperature and pressure conditions.The effect of different fluidization time on the degree of Mg O deliquescence was also investigated.Microscopic observation of the product was carried out by means of transmission electron microscope,the activity of the product was detected by citric acid method and the product was characterized by specific surface area meter.Results showed that with the extension of fluidization time,M...
