对磷酸和单宁酸作为防锈剂进行了研究。研究了这些产物与不同氧化铁和氢氧化物混合时的相互作用和相变动力学。红外光谱（IR）结果表明，各配方对酸的反应性最强的是绢云母（γ-FeOOH），其次是针铁矿（α-FeOOH）和磁铁矿（Fe3O4）。无单宁酸诱导的蛭石向磁铁矿转变。
Research was performed on both phosphoric and tannic acids as chemicals for rust transformation. The interaction and phase transformation kinetics of the reaction between these products when mixed with different iron oxides and oxyhydroxides were studied. Infrared spectroscopy (IR) results of all formulations indicated that lepidocrocite (γ-FeOOH) was the most reactive to acids followed by goethite (α-FeOOH) and magnetite (Fe3O4). No lepidocrocite to magnetite transformation induced by tannic acid.
