氧化镁促硬效果好,但生成的磷酸镁耐火性差,使热态强度下降。其硬化时间随气温不同而变化显著。磷酸铝,磷酸与骨料反应,因生成不溶物会导致材料产生时效变化,当原料中所含铁分的反应会影响时效变化,混练泥料时,对混练机有腐蚀作用,导致设备损坏,所以必须加入时效抑制剂及有缓解作用的外加剂。磷酸盐结合浇注料的干燥温度低时,易形成吸湿性化合物焦磷酸。存放期间吸附空气中水分还原成正磷酸破坏胶结性。因此磷酸盐结合浇注料应经过450~500摄氏度左右干燥,形成磷酸铝或偏磷酸铝。水玻璃结合浇注料的骨料和粉料来源广泛,既可用硅酸铝质,硅质,半硅质,还可以用于镁质,镁铝质等耐火浇注料。由于水玻璃较黏稠,拌料和振动时间增长。20世纪70年代出现速溶性固体水玻璃。

磷酸盐耐火浇注料的组成与一般耐火浇注料相近。磷酸铝、磷酸与中性及酸性骨料在常温条件下只发生缓慢反应,为赋予浇注料常温硬化性能,必须使用硬化剂。硬化剂有活性氢氧化铝、滑石、氟化铵、氧化镁、碱性氯化铝、纯铝酸钙水泥等。氧化镁是普遍应用的硬化剂,促硬效果好,但反应生成的磷酸镁耐热性差,致使热态强度下降,以氧化镁作硬化剂其硬化时间随气温不同而变化显著。
