     無水純凈的磷酸為無色的斜方柱狀晶體,易溶于水,熔點42℃,P205=72%。磷酸一般為無色粘稠的液體,是不揮發非氧化性中強酸。磷酸為高沸點的三元酸(k1-7.1X10-3,k2=6.3X10-8、k3=4.4×10-3),與大多數金屬易迅速反應,析出氫氣和生成相應的磷酸鹽:與堿性氧化物反應可以生成三種類型的鹽(正鹽、一氫鹽、二氫鹽),至于生成那種鹽主要根據磷酸與堿的量來確定,一般與弱堿性

    磷酸鹽結合的高鋁水泥質耐火材料的硬化機理是磷酸鹽膠結劑與物料的化學反應和黏附膠結的結果。化學反應是由于生成含水的磷酸二氫鋁,磷酸一氫鋁以及它們的聚合作用。膠結劑中的正磷酸和磷酸鹽完全中和時則生成不溶于水的磷酸鋁,從而材料具有強度。
