Ihe nkedo phosphate na-ezo aka na ihe nkedo jikọtara ya na phosphoric acid ma ọ bụ phosphate, na usoro siri ike ya na-emetụta ụdị ihe nkedo eji na usoro siri ike.
Ihe nkedo nke phosphate castable nwere ike ịbụ phosphoric acid ma ọ bụ ihe ngwọta nke aluminom dihydrogen phosphate mepụtara site na mmeghachi omume nke phosphoric acid na aluminum hydroxide. N'ozuzu, ihe nkedo na aluminom silicate anaghị emeghachi omume na ọnụ ụlọ okpomọkụ (ma e wezụga ígwè). A na-achọ ikpo ọkụ iji kpoo mmiri na ikpokọta ihe nkedo ma jikọta ntụ ntụ ọnụ iji nweta ike na okpomọkụ ụlọ.
Mgbe a na-eji coagulant eme ihe, a naghị achọ ikpo ọkụ, na ezigbo magnesia ntụ ntụ ma ọ bụ ciment alumina dị elu nwere ike ịgbakwunye ngwa ngwa coagulation. Mgbe a na-agbakwunye ezigbo ntụ ntụ magnesium oxide, ọ na-eme ngwa ngwa na phosphoric acid na-etolite, na-eme ka ihe ndị na-emegharị ihe na-edozi ma sie ike. Mgbe a na-agbakwunye ciment aluminate, a na-emepụta phosphates nwere ezigbo gelling, phosphates nke nwere mmiri dị ka calcium monohydrogen phosphate ma ọ bụ diphosphate. Calcium hydrogen, wdg, na-eme ka ihe ahụ sie ike ma sie ike.
Site na usoro siri ike nke phosphoric acid na phosphate refractory castables, a maara na ọ bụ naanị mgbe mmeghachi omume mmeghachi omume n'etiti ciment na nchịkọta refractory na ntụ ntụ kwesịrị ekwesị n'oge usoro ikpo ọkụ nwere ike ịmepụta ihe nkedo nke ọma. Otú ọ dị, a na-ebute ngwa ngwa ndị na-emegharị ihe n'ime usoro ịkụcha ihe, ịkụcha bọl na ịgwakọta. Ha ga-emeghachi omume na onye na-emepụta ciment ma hapụ hydrogen n'oge ngwakọta, nke ga-eme ka ihe nkedo refractory zaa, tọpụ ihe owuwu ahụ ma belata ike mkpakọ. Nke a adịghị mma maka mmepụta nke phosphoric acid nkịtị na phosphate refractory castables.
