Microwave-Hydrolysis Synthesis Spindle-Type Hematite Particles

Abstract

Abstract: To study the microwave effects to the formation of nanoparticles, the hydrolysis reaction of FeCl₃ with NaH₂PO₄ 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 H₂PO^-₄ during the hydrolysis process were also discussed.

Key words: microwave, nanophase spindle-type colloidal hematite, sodium dihydrogen phosphate
