在空气中易潮解，易溶于水，20℃时每升水溶解973.2克，80℃时每升水溶解1744克，1％溶液的PH值为5.5-6.5左右，不溶于有机溶剂，在中性介质中，水解最终产物为正磷酸盐。 吸湿性很强，露置于空气中能逐渐吸收水分而呈粘胶状物。能与碱土金属化合成可溶性复盐，因此有溶解水垢的功能，是一种良好的软水剂。 主要用于锅炉用水软水剂、印染染浴的软水剂和造纸扩散剂。还用于缓蚀剂、浮选剂、分散剂和高温结合剂。其它用于洗涤器皿以及化学纤维中用以除去浆粕中的铁质。还用于土壤分析。 Sodium Hexametaphosphate (SHMP) can be used as: A reagent for the oxidation of aldehydes to carboxylic acids in the presence of H2O2 as an oxidant. A polymeric stabilizing and protecting agent in the synthesis of SHMP-stabilized gold nanoparticles (Au–SHMP) applicable in the development of biocompatible molecular probes. A capping agent in the synthesis of sterically stabilized luminescent nanoparticles of manganese doped zinc sulfide (ZnS:Mn2+). A stabilizing agent in the synthesis of barium sulfate nanoparticles by precipitation method.
