Microwave-Hydrolysis Synthesis Spindle-Type Hematite Particles
微波水解法制备针形α-Fe2O3纳米粒子

To study the microwave effects to the formation of nanoparticles, the hydrolysis reaction of FeCl 3 with NaH 2PO 4 to get spindle-type colloidal hematite particles under microwave radiation was reported We found that the reaction velocity increased greatly, and the reaction conditions, for example, the acidity of the solution, concentration ratio of the components and the microwave radiation time had important effects on the nanoparticle formation and the morphology Here, the roles of microwave and H 2PO - 4 during the hydrolysis process were also discussed
