Study on Preparation of Nanosized Sb and Dispersion of Sb in Liquid Media

Nano antimony particles with different morphology and size were prepared by electrochemical method(Electrodeposition),while the surface was modified by using OP-10.Some methods such as TEM,XRD,FTIR were used for the morphology,size and coating effects analysis of the nanometer-sized Sb particles.The results showed that there were time effects and current effects when antimony nanoparticles were synthesized.With increasing reaction time,the size of nano-antimony particle became larger and,to some extent,agglomerating phenomenon of nano-antimony particle occurred.When the current density changed within a certain range,the suitable increase of the current density was conducive to the formation of nano-antimony particles.The surface modification of nano-particles of antimony was obtained mainly by coating of OP-10 through chemical absorption between OP-10 long-chain molecular structure and nano-antimony particle,interaction of hydrogen bond and van der waals force among OP-10 long-chain alkyl molecular,mutual tangle of molecular chain and mutual permeation of C—H bond,while the bond of ether playing a role during the reaction.The dispersion and stability of nano antimony particles in the pure liquid paraffin oil related to their dosage,and the optimum amount is 0.5%.
