Muri rusange, amatafari maremare ya aluminiyumu ntagomba gukoreshwa mu itanura ry’ikirere cya alkaline. Kubera ko icyuma cya alkaline na aside nabyo bifite chlorine, kizinjira mu mpande z’amatafari maremare ya aluminiyumu mu buryo bw’ubushyuhe, bigatuma amatafari adashobora kwangirika agwa.
Amatafari ya aluminiyumu menshi nyuma yo kwangirika k'ikirere cya alkali ni imiyoboro itambitse. Isuri igizwe n'ibikomoka ku ivumbi ry'amavuta, imyuka itwika, n'ibikomoka ku alkali mu bindi bicuruzwa. Ibi bice bigira ingaruka ku kirahure n'amabuye ya mullite mu itafari rya aluminiyumu rinini.
Amatafari ya aluminiyumu menshi yangiritse azagaragara hejuru y’ubutaka. Imyuka itwika izatanga nitrate nziza, ikava mu mwenge w’amatafari ya aluminiyumu menshi; uburyo ibimera bya barafu byakozwe buzahinduka ikindi cyiciro gishya. Iyo nitrile zidafite amazi zihuye n’umukungugu wakozwe, hazabaho uburyo bwo kurwanya umwuka ushyushye, bigatuma amatafari ya aluminiyumu menshi acika cyangwa agagwa. Byongeye kandi, ingese y’ubushyuhe nayo ni mbi cyane ku ngese y’amatafari adashobora kwangirika. Kubera ko Fang quartz, Skywine, na quartz crystal silica yangiritse. Gukoresha amatafari y’umuriro bizaba bikomeye kuruta noodles zikonje.
Kwangirika kw'amatafari ya silicon dioxide nabyo ni bibi cyane. Silika ishongeshwa mu gice cy'amatafari ya aluminiyumu ifite amatafari menshi. Nitrati ishongeshwa n'amabuye ya silicon afite aho ashongeshwa cyane bigira igice kinini cy'amazi. Uko silika iba nyinshi mu matafari, ni ko igice cy'amazi kiba kinini. Igice cy'amazi menshi kizahindura amatafari ya aluminiyumu ifite amatafari menshi. Silika ya siliyumu nayo yangirika ku matafari. Kubera ko siliyumu yigenga ikoreshwa, igice cya Mo Lai Shi kizasenyuka. Nyuma yo gusubiza lickle nitrate na mullite stone bishobora gutuma amatafari ya aluminiyumu afite amatafari menshi yangirika.
Amatafari maremare ya aluminiyumu arwanya ubushyuhe bwinshi n'ubukonje bwinshi. Akoreshwa cyane mu miterere y'amatafari atandukanye yo mu nganda, nk'amatafari ashyushye, amatafari ashyushye, n'amatafari azunguruka. Ariko, mu kirere cy'inganda gifite ikirere cya alkaline, ikoreshwa ry'amatafari maremare ya aluminiyumu ni rike.
Imiterere y’ibinyabutabire by’amatafari menshi ya alumina ituma arwanya ingaruka z’ibidukikije birimo aside. Ariko, mu bidukikije birimo alkali nyinshi, nk’amatanura ya sima cyangwa amatanura y’ibirahure, amatafari menshi ya aluminiyumu ahura n’aside ya alkali metal, bigatuma amatafari acikamo ibice akanasenyuka. Uburyo amatafari ya Al2O3 akorana n’aside ya alkali metal bukunze gutuma habaho gel ya alkali aluminosilicate, ifite aho ishongera cyane kandi ishobora gutemba mu buryo bworoshye mu miyoboro.
Kugira ngo iki kibazo gikemuke, hakoreshejwe ingamba nyinshi zo kunoza ubudahangarwa bw'amatafari menshi ya aluminiyumu n'ibidukikije bya alkali. Uburyo bumwe ni ugushyira magnesia cyangwa spinel ku matafari menshi ya aluminiyumu. Magnesia cyangwa spinel bikorana na okiside y'icyuma cya alkali kugira ngo bikore ibice bya spinel bihamye, bishobora kongera ubudahangarwa bw'amatafari ya Al2O3 ku gucika kw'amatafari bitewe n'ihinduka ry'amatafari ya alkali. Ubundi buryo ni ugushyira agatambaro gakingira ku buso bw'amatafari menshi ya aluminiyumu kugira ngo hirindwe ko habaho impanuka ku bidukikije bya alkali.
Muri make, amatafari maremare ya aluminiyumu ntakoreshwa cyane mu miterere y’amatafari yo mu nganda. Kugira ngo amatafari ya Al2O3 yongere imbaraga zo guhangana n’amatafari mu nganda zirimo aluminiyumu, ni ngombwa kongeramo imyunyu ngugu cyangwa irangi kugira ngo hirindwe ingaruka mbi ziterwa na okiside z’icyuma za alkali. Ni ngombwa guhitamo ibikoresho bikwiye byo gukoresha mu miterere y’amatafari yo mu nganda kugira ngo ugabanye ibyago bishobora kubaho kandi uzigame ikiguzi.
