Information

Due to the decomposition of CO2 and H2O, MgO forms a porous crystal structure, which is not dense. The product has good activity and high dispersion (180m2/g). This refers to the temperature of 400 ° C ~ 600 ° C. At this time, the product is finely ground at room temperature. It hydrates in a few minutes. Therefore, a good calcination process should control the temperature at 400 ° C ~ 600 ° C, which saves energy and the quality of the product is good. When the temperature is higher than 900 ℃, the crystal densification dispersion is only 3m2/g at 1300 ℃, and it takes 75 days to hydrate 95% of magnesium oxide at room temperature.
