I-refractory yepulasitiki engagqoki enamandla aphezuluiwuhlobo lwezinto eziphikisayo ezingakakhiwe ezidizayinelwe ngokukhethekile ukusetshenziswa emazingeni okushisa aphezulu, alimaza kakhulu, nezimo eziguguleka kakhulu. Ifaka ipulasitiki eqinile, ukwakhiwa okulula, amandla aphezulu, nokumelana nokugqokwa okuhle kakhulu, futhi isetshenziswa kabanzi njengolwelwesi lwangaphakathi lwemishini ebalulekile yokushisa okuphezulu ezimbonini ezifana namandla, i-metallurgy, usimende, nobunjiniyela bamakhemikhali.

Izinto zokusetshenziswa eziyisisekelo zamandla aphezulu kanye nezinto zepulasitiki ezingagugi:

Ama-aggregates kanye nezimpushana: I-high-alumina bauxite, i-corundum, i-silicon carbide, isihlabathi se-chromite, nezinye izinto eziqinile ezingagugi zikhethwa ukuze zenze uhlaka lwamathambo, okunquma ukumelana nokugqoka kanye nokumelana nokushisa okuphezulu.
Izibophezelo: Kukhona ama-hydraulic binders (njengosimende we-aluminate) nezibophezelo zamakhemikhali (njenge-phosphoric acid ne-phosphate), ezingelapheka ekamelweni lokushisa ngaphandle kokucwiliswa kwezinga lokushisa eliphezulu.
Izingxube: Engeza izinciphisi zamanzi, ama-plasticizer, nama-anti-cracking ukuze uthuthukise ukusebenza nokumelana nokuqhekeka ngesikhathi sokwakha; hlanganisa imicu yensimbi nemicu ye-ceramic ukuze kuthuthukiswe ukumelana nomthelela kanye nokumelana nokushaqeka okushisayo.

Izici ezisebenzayo zezinto zepulasitiki ezingagqoki eziqinile:

"Plastiki refractory impahla":ibhekisela ezintweni eziphikisayo ezibonisa ipulasitiki enhle ekamelweni lokushisa (elifana ne-plasticine), futhi lingakhiwa ngezindlela ezifana ne-ramming ne-coating, ngaphandle kokudinga ukudlidliza ekubunjweni.
"Amandla aphezulu nokumelana nokugqoka": Ngokungeza ama-aggregates aqinile njenge-corundum, i-silicon carbide (SiC), i-mullite, ne-high-alumina clinker, futhi ukuwahlanganisa ne-phosphate, usimende we-calcium aluminate, noma ama-organic binders, ifinyelela amandla aphezulu okucindezela ekamelweni lokushisa/ izinga lokushisa eliphezulu (≥60 MPa ngemva kokumiswa ku-MPa 110≥8 ngemva kokumiswa kwe-MPa 110≄8 1350 ℃) nokugqokwa okuhle kakhulu ukumelana (ukulahlekelwa kokugqoka ≤5 cm³, kungcono kakhulu kunokuphonswa okujwayelekile)

Umehluko oyinhloko phakathi kwepulasitiki engagugi namandla aphezulu kanye nepulasitiki evamile uku:

Ingxenye yokuqinisa ukumelana nokugqoka:Izinto zepulasitiki ezingagqoki eziqine kakhulu zithuthukiswa ngezihlanganisi ezimelana nokuguga okuqinile njenge-silicon carbide ne-corundum, noma imicu yensimbi engagqoki, okuholela ekuphikiseni ukugqokwa okuphindwe izikhathi ezingu-2-3 kunento evamile yepulasitiki.
Izinkomba zamandla:Ibonisa amandla acindezelayo aphezulu kuwo womabili amakamelo namazinga okushisa aphezulu, okuyenza ifaneleke izimo zokusebenza ezinzima ezinomthelela omkhulu kanye nemithwalo esindayo. Ngokuphambene, izinto ezijwayelekile zepulasitiki zifaneleka kakhulu ukufakwa kwe-thermal noma ulwelwesi olusizayo ngokuguga okuphansi.
