The preparation of AgI Nano-powder by Non-aqueous Solvent method

摘要

A new technique on the preparation of Silver iodide nano-powder from salt of silver and iodide ethanolrnsolutions has been developed. Optimum preparing conditions were obtained through a series ofrnexperiments and Latin square experiments. Under these conditions, the yield of CuI reached 95%.Thernproduct was characterized. The results show that the product takes a near-spherical shape with an averagernparticle size of 30nm. Optimum preparing conditions is C_(kI)=0.009mol/l, C_(AgNO3)=0.009mol/l, T=40℃,rnt=2h.
