Ana iya amfani da sinadarin phosphate wajen yin castable wanda aka haɗa shi da sinadarin phosphoric acid ko phosphate, kuma tsarin taurarewarsa yana da alaƙa da nau'in abin ɗaurewa da aka yi amfani da shi da kuma hanyar taurarewa.
Mai ɗaure sinadarin phosphate castable zai iya zama phosphoric acid ko kuma gaurayen maganin phosphate na aluminum dihydrogen wanda aka samar ta hanyar amsawar phosphoric acid da aluminum hydroxide. Gabaɗaya, mai ɗaure da aluminum silicate ba sa amsawa a zafin ɗaki (sai dai ƙarfe). Ana buƙatar dumama don bushewa da mannewa da haɗa foda mai haɗuwa don samun ƙarfi a zafin ɗaki.
Idan ana amfani da coagulant, ba a buƙatar dumamawa, kuma ana iya ƙara foda mai kyau na magnesia ko siminti mai yawan alumina don hanzarta coagulation. Idan aka ƙara foda mai kyau na magnesium oxide, yana amsawa da sauri tare da phosphoric acid don samar da shi, yana sa kayan da ba su da ƙarfi su yi ƙarfi su kuma taurare. Idan aka ƙara simintin aluminate, ana samar da phosphates masu kyawawan halayen gelling, phosphates masu ɗauke da ruwa kamar calcium monohydrogen phosphate ko diphosphate. Hydrogen calcium, da sauransu, suna sa kayan su taru su kuma taurare.
Daga tsarin taurarewar phosphoric acid da phosphate refractory castables, an san cewa sai lokacin da yawan amsawar da ke tsakanin siminti da gauraye masu refractory da foda ya dace a lokacin dumama ne za a iya samar da kyakkyawan refractory castable. Duk da haka, ana iya shigar da kayan da ba su da refractory cikin sauƙi wajen niƙa, niƙa ball da haɗawa. Za su yi aiki tare da simintin kuma su saki hydrogen yayin haɗawa, wanda zai sa refractory castables ya kumbura, ya rasa tsarin kuma ya rage ƙarfin matsi. Wannan ba shi da kyau ga samar da phosphoric acid da phosphate refractory castables na yau da kullun.
