| Abstract: | Cuprous thiocyanate nanoparticles were prepared straight by inorganic dispersant,in which CHSO4 is f reactant, Na2SO3 is reducing agent, and NaSCN is precipitating agent. The factors that influence the size of particles such as quantities of dispersant,the concentration of reactants and pH value were investigated. The best conditions are that the weight percent of dispersant is 0. 03 %-0. 06%, the concentration of reactants is 0.3 mol/L and the pH value is 8-10. TEM, SEM, IR and XRD were used to characterize the particles. The results show that the particles are fine and the size of the particles is 80 nm. |
