摘要
以磷铁为原料,探讨了Fe3+-PO43--NH3·H2O,Fe3+-PO43--Na2HPO4,Fe3+-PO43--分散剂A这3种体系对磷酸铁结晶产物性能的影响。经比较发现,在Fe3+-PO43--分散剂A体系中制备出的磷酸铁热稳定性好,磷元素与铁元素物质的量比接近于1,颗粒呈现微球状,并对该产品进行元素分析与结构分析。
Ferro-phosphorus was used as raw material to prepare iron phosphate.The influence of three different media,which include Fe^3＋-PO4^3--NH3· H2O, Fe^3＋-PO4^3--NazHPO4, and Fe^3＋-PO4^3--dispersant A on properties of iron phosphate crys-tals was discussed.After comparison, it was found a kind of micro-spherical iron（Ⅲ） phosphate with good thermal stability and amount-of-substance ratio of P to Fe close to 1 had been prepared in Fe^3＋-PO4^3--dispersant A system.Analysis on the chemical composition and structure of the product was also made.
