Fosphate castable e faasino i se castable tu'ufa'atasi ma le phosphoric acid po'o le phosphate, ma o lona fa'ama'a'a faiga e feso'ota'i ma le ituaiga o fusi fa'aaoga ma le auala fa'ama'a'a.
O le fusifusia o le phosphate castable e mafai ona avea ma phosphoric acid poʻo se fofo fefiloi o le alumini dihydrogen phosphate e maua mai i le tali atu o le phosphoric acid ma le alumini hydroxide. E masani lava, o le mea faʻapipiʻi ma le alumini silicate e le tali i le vevela o le potu (sei vagana ai le uʻamea). E mana'omia le fa'avevela ina ia fa'amama ma fa'aputu le mea fa'apipi'i ma fa'apipi'i fa'atasi le pauta fa'atasi ina ia maua ai le malosi i le vevela o le potu.
A faʻaaogaina le coagulant, e le manaʻomia le faʻamafanafanaina, ma e mafai ona faʻaopopoina le paʻu magnesia lelei poʻo le sima alumina maualuga e faʻavave ai le faʻamalo. A fa'aopoopo i ai le pauta lelei o le magnesium oxide, e vave ona fa'agaioi ma le phosphoric acid e fa'atupu, ma mafua ai ona fa'atutu ma fa'ama'a'a mea fa'ama'a. Pe a faʻaopoopo le sima aluminate, phosphates ma mea lelei gelling, phosphates vai e pei o le calcium monohydrogen phosphate poʻo le diphosphate e fausia. O le calcium hydrogen, ma isi mea, e mafua ai ona fa'afefe ma fa'ama'a'a mea.
Mai le faiga faʻamaʻaʻaina o le phosphoric acid ma le phosphate refractory castables, ua iloa e naʻo le taimi o le tali i le va o le sima ma le faʻapipiʻi faʻaputu ma paʻu e talafeagai i le taimi o le faʻavevelaina e mafai ona faʻatupuina se castable refractory sili ona lelei. Ae ui i lea, o le refractory mata e faigofie ona aumaia i le faagasologa o le pulverization, polo milling ma fefiloi. O le a latou tali atu i le sima sui ma faʻasaʻo le hydrogen i le taimi o faʻafefiloi, lea o le a mafua ai ona fulafula le castable refractory, tatala le fausaga ma faʻaitiitia le malosi faʻamalosi. E le lelei lenei mea mo le gaosiga o mea masani phosphoric acid ma phosphate refractory castables.
