Amatafari yo mu ibumba akozwe mu buryo bwa refractory
Amatafari y'ibumba atwikwani ibikoresho birwanya aruminiyumu bifite Al₂O₃ 35%–45%. Bikorwa ahanini muri kaolini, bigakorwa mu buryo bugaragara, bikamishwa, hanyuma bigashyushwa ku bushyuhe buri hejuru bwa 1300–1400℃. Mu gihe cyo gutwika, hakorwa kristu za mullite. Hamwe n'ubudahangarwa bwa 1690–1730℃, amatafari y'ibumba ashyirwa mu byiciro by'ibikomoka ku budahangarwa budafite aside nyinshi.
Gushyira mu byiciro
Amatafari y'ibumba rikoresha umuriro ashobora gushyirwa mu byiciro bine: asanzwe, acucitse, adatemba cyane, kandi arwanya ubushyuhe, afite ingano zitandukanye z'ibipimo bya Al₂O₃ kuva kuri 25% kugeza kuri 45%. Dukurikije uko ikoreshwa rikorwa, agabanyijemo ibice bitatu: iby'amatafari akoresha umuriro, amatafari akoresha umuriro, n'amatafari y'ibirahure.
Ibiranga by'ingenzi:
Amatafari y'ibumba akoreshwa mu muriro agaragaza ubudahangarwa bwiza ku ifu y'aside na gazi isanzwe, ariko afite ubudahangarwa buke ku bintu bya alkaline. Afite ubudahangarwa bwiza ku bushyuhe: mu bushyuhe buri hagati ya 0–1000℃, ingano yayo irakura neza uko ubushyuhe bwiyongera, hamwe n'umuvuduko wo kwaguka wa 0.6%–0.7%, ni ukuvuga hafi kimwe cya kabiri cy'amatafari ya silica. Ariko, ubushobozi bwayo bwo kutarenza umutwaro buri munsi ya 200℃ ugereranyije n'ubw'amatafari ya silica, kandi ingano yayo igabanuka iyo ubushyuhe burenze 1200℃.

Inganda z'ibyuma
Mu nganda zikora ibyuma, amatafari akoreshwa mu ibumba akoreshwa cyane cyane mu bikoresho nk'amatanura akoreshwa mu muriro, amatanura akoreshwa mu muriro n'amatanura y'ibirahure. Amatanura akoreshwa mu ibumba ashobora kwihanganira ubushyuhe bwinshi n'ikirere cyangiza kugira ngo arinde imiterere y'itanura; amatanura akoreshwa mu ibumba akoreshwa mu matanura akoreshwa mu muriro kugira ngo akore neza; amatanura manini akoreshwa mu matanura y'ibirahure akoreshwa mu matanura ashongesha ibirahure kugira ngo ahamye kandi arwanye umuriro mu gihe cy'ubushyuhe bwinshi.
Inganda z'ibinyabutabire
Mu nganda zikora imiti, amatafari akoreshwa mu ibumba akoreshwa nk'ibikoresho byo gushyiramo ibikoresho nk'ibikoresho bitanga ingufu, amatanura n'amatanura akoreshwa mu gutunganya. Ibi bikoresho bikora muriubushyuhe bwinshi n'ikirere cyangiza, hamwe n'amatafari y'ibumba ashobora kugabanya ubushyuhe no kunoza imikorere myiza y'ingufu.
Inganda za Ceramic
Mu nganda zikora ibumba, amatafari akoreshwa mu ibumba akoreshwa mu gukingira inkuta no ku bisenge byaamatanura yo gutwika amatanura kugira ngo abungabunge ubushyuhe bwinshi mu itanura no guteza imbere gutwika ibikoresho bya ceramic. Ibumba rikomeye n'ibumba rito bikoreshwa nk'ibikoresho fatizo byo gukora ceramic zikoreshwa buri munsi, ceramic zo mu bwubatsi n'inganda.ibumba.
