用穆斯堡尔效应研究了α—Fe和铁锈的各主要组份(α-,γ-,δ-,am-FeOOH;α-,γ-Fe_2O_3和F_3O_4)与商品磷酸系锈控涂料主要活性组份—20%磷酸酒精液的作用,结果表明除Fe_3O_4的作用产物系三价铁无定形磷酸盐外。其余产物都为酸式磷酸盐FeH_3(PO_4)_2·2 1/2H_2O。另外,在Fe_3O_4和在α-Fe的反应产物中还存在多种高自旋二价铁的产物。环境中的NaCl及H_2O会不同程度地改变上述反应产物的结构,而O_2对二价铁磷酸盐变成三价铁磷酸盐是必须的。作者用形核长大和高聚物聚沉两种不同沉淀机制对以上结果作了解释。
The main activities of α-Fe and rust (α-, γ-, δ-, am-FeOOH; α-, γ-Fe 2 O 3, and F 3 O 4) were compared with those of commercial phosphoric acid system rust control coatings by Mossbauer effect Components -20% phosphoric acid alcohol solution, the results show that in addition to the role of Fe_3O_4 ferric iron phosphate amorphous system. The remaining products are acid phosphate FeH_3 (PO_4) _2 · 2 1 / 2H_2O. In addition, there are many products of high spin rate ferrous iron in the reaction product of Fe_3O_4 and α-Fe. The environment of NaCl and H_2O will change the structure of the above reaction products to varying degrees, and O_2 ferric iron phosphate into ferric phosphate is necessary. The authors explain the above results by using two different precipitation mechanisms: nucleation and polymer precipitation.
