Effect of stearic acid, zinc stearate coating on the properties of synthetic hydromagnesite

▶ Surface of the synthetic hydromagnesite was changed from hydrophilic to lipophilic. ▶ The flowability of the surface modified synthetic hydromagnesite was improved. ▶ The surface modifiers and the modifying processing did not affect the crystal structure. ▶ The surface modifier had no obvious influence on the powder's degradation pathway.
