Nakuba intengo yesihlabathi se-ceramic iphakeme kakhulu kunesihlabathi se-silica nesihlabathi se-quartz, uma isetshenziswe kahle futhi ibalwa ngokucophelela, ayikwazi nje ukuthuthukisa ngokuphawulekayo ikhwalithi ye-castings, kodwa futhi inciphise izindleko zokukhiqiza.
1. I-refractoriness yesihlabathi se-ceramic iphakeme kunesihlabathi se-silica, futhi ukuhlangana kokugcwalisa ngesikhathi sokubunjwa kuphezulu, ngakho-ke izinga eliphezulu le-castings lingathuthukiswa futhi izinga le-scrap ekukhiqizeni lingancishiswa;
2. Isihlabathi se-ceramic esiyindilinga sine-fluidity enhle. Ngokulingisa okumile okuyinkimbinkimbi, kulula ukugcwalisa izingxenye eziqinile okunzima ukuzigcwalisa, njengama-engeli angaphakathi, ama-recesses ajulile, nezimbobo eziyisicaba. Ngakho-ke, kunganciphisa kakhulu ukukhubazeka kokupakisha isihlabathi kulezi zingxenye, futhi kunciphise kakhulu umsebenzi wokuhlanza nokuqeda;
3. Ukumelana nokuchotshozwa okuhle, izinga eliphezulu lokululama, kanye nokukhishwa kwemfucuza ngendlela ehambisanayo;
4. Izinga lokunweba okushisayo lincane, ukuzinza kwe-thermal kuhle, futhi ukuguqulwa kwesigaba sesibili ngeke kubangele amaphutha okwandisa, okuthuthukisa kakhulu ukunemba kobukhulu.
Ubuso besihlabathi se-ceramic bushelelezi kakhulu, futhi ifilimu yokunamathisela ebusweni bezinhlamvu zesihlabathi ingasuswa ngokungqubuzana okuncane kwesihlabathi esidala. Izinhlayiya zesihlabathi se-ceramic zinokuqina okuphezulu futhi akulula ukuphuka, ngakho-ke ikhono lokubuyisela kabusha lesihlabathi se-ceramic linamandla ikakhulukazi. Ngaphezu kwalokho, zombili izindlela zokuvuselela ezishisayo kanye nezindlela zokuphinda zenziwe kabusha zifanele isihlabathi se-ceramic. Uma kuqhathaniswa, ngemva kokuba i-Foundry isebenzisa isihlabathi se-ceramic, ingakwazi ukuqoqa isihlabathi esidala ngaphandle kwezindleko eziningi. Idinga kuphela ukususa ingxenye eboshiwe yendawo yesihlabathi, bese ingavuselelwa futhi isetshenziswe kabusha ngemva kokuhlolwa. Ngale ndlela, isihlabathi se-ceramic singaphinda sisetshenziswe futhi sisetshenziswe ngokuphindaphindiwe. Ngokuya ngezinga lekhwalithi yemishini yokubuyisela kabusha, izikhathi zokubuyiselwa kwesihlabathi se-ceramic ngokuvamile izikhathi ezingu-50-100, futhi amanye amakhasimende aze afinyelele izikhathi ezingu-200, okunciphisa kakhulu izindleko zokusetshenziswa, ezingenakushintshwa ezinye izihlabathi ezitholakalayo.
Ukukhiqizwa kwe-casting ngesihlabathi se-ceramic esibuyiselwe izikhathi ezingaphezu kuka-20.
Kungashiwo ukuthi ukusetshenziswa kwesihlabathi se-ceramic, ukuvuselelwa kabusha kuyithuluzi elikhulu, elingenakuqhathaniswa nesinye isihlabathi se-Foundry.
