Abstract—

This paper considers approaches to the preparation of potential reagents for precipitation enhancement processes. New reagents have the form of hybrid powder materials produced via physical attachment of silver iodide crystals to colloidal silica particles. In our work, hybrid powder is thought of as a combination of an inert matrix (colloidal silica) and a modifier (silver iodide as an active reagent). We demonstrate that the way in which composite powders are synthesized influences the phase state of the modifier. We have studied structural characteristics of the synthesized powder materials. The results demonstrate that increasing the percentage of silica in the composition of the powders leads to predominant formation of the hexagonal crystalline phase of silver iodide.

胶体二氧化硅和碘化银杂化粉末材料的合成与结构性能

摘要-

本文考虑了用于沉淀增强过程的潜在试剂的制备方法。新试剂具有混合粉末材料的形式，该混合粉末材料是通过碘化银晶体与胶体二氧化硅颗粒的物理附着而产生的。在我们的工作中，杂化粉末被认为是惰性基质（胶体二氧化硅）和改性剂（碘化银作为活性试剂）的组合。我们证明合成复合粉末的方式会影响改性剂的相态。我们已经研究了合成粉末材料的结构特征。结果表明，增加二氧化硅在粉末组合物中的百分比导致碘化银的六方晶相的主要形成。
