Phosphorus-31 nuclear magnetic resonance spectroscopy of phosphoric acid solutions containing zinc and aluminium indicates that zinc forms simple salts in solution, whereas aluminium forms a number of complexes, some of which are polymeric. The formation of the aluminophosphoric acid complexes controls the gelation and strengthening of the dental silicate cement and prevents the formation of crystalline zinc phosphate in the zinc phosphate cement.
对含有锌和铝的磷酸溶液进行磷-31核磁共振光谱分析表明，锌在溶液中形成简单盐类，而铝则形成多种络合物，其中一些是聚合物。铝磷酸络合物的形成控制着牙科硅酸盐水泥的胶凝和强化，并防止磷酸锌水泥中形成磷酸锌晶体。
