Amatafari y’alumina y’agaciro kanini-ni ubwoko bw’ibikoresho bishobora gusha bifise ishusho biva mu gutera ibumba ridashobora gusha canke ibindi bikoresho bitagira umuriro ku bushuhe bwinshi; ziri mu muryango w’ibintu vy’aluminosilicate. Amatafari ashobora gusha ni ibikoresho bitagira ubuzima bitagiramwo ivyuma biboneka mu bwoko butandukanye, harimwo amatafari y’ivyuma vy’agaciro kanini, ibumba, magnesia, corundum, mullite, n’ivyuma vy’ivyuma vy’agaciro kanini. Kubera ubushobozi bwayo bwo guhangana n’umuriro, amatafari y’alumina menshi-arakoreshwa cane mu bwoko butandukanye bw’amatafari ashobora guhangana n’umuriro. Dushingiye ku ngingo mfatirwako z’ibikoresho bishobora guhangana n’ivyuma vy’alumina vyinshi, ibirimwo Al2O3 ni vyo bifadika cane mu gushikiriza ibikoresho. Mu buryo bwihariye, amatafari y’alumina menshi-ashirwa mu bice bitatu: Igice ca I (Al2O3 > 75%), Igice ca II (Al2O3 kiri hagati ya 60% na 75%), n’Igice ca III (Al2O3 kiri hagati ya 48% na 60%).
Nk’ubwoko bw’ibikoresho bishobora gusha, amatafari y’alumina menshi-akoreshwa canecane na Al2O3. Ugereranije n’amatafari y’ibumba n’amatafari y’igice ca -silika, amatafari y’alumina menshi cane yerekana ubushobozi bwo guhangana n’umuriro kandi rero ashirwa mu rutonde rw’ibikoresho vy’agaciro kanini bishobora guhangana n’umuriro. Ivyo bifise Al2O3 vyinshi bituma zigira ibiranga hafi-utagira aho zigarukira, bikaba bishoboza guhangana n’ugusenyuka kw’ibisigazwa vy’amazi n’ibisigazwa vy’amazi. Ariko rero, birabereye kumenya ko naho zirimwo SiO2, ubushobozi bwazo bwo guhangana n’ivyuma vy’ishimikiro buri hasi gatoyi y’ubushobozi zishobora guhangana n’ivyuma vy’aside. Hashingiwe ku birimwo Al2O3, amatafari y'alumina menshi ashobora guca mu bice nka 55, 65, 75, na 80.
Amatafari y’aluminium menshi-ashirwa mu bice bitandukanye bivanye n’ivyo Al2O3 (aluminium oxide) arimwo. Muri izo, amatafari y’i corundum-afise aluminium 90% canke irenga-aserukira urugero rwo hejuru rw’amatafari y’aluminium menshi-. Amatafari y'aluminium "y'agaciro kadasanzwe" arimwo nibura 85% vy'aluminium, mu gihe amatafari y'agaciro ka I arimwo ibirenga 75%; Amatafari yo mu rwego rwa II n’urwa III arimwo nibura 65% na 55% vy’aluminium. Ivyo bipimo bitandukanye bitanga ubushobozi butandukanye bwo guhangana n’umuriro kugira ngo bishobore gushitsa ibisabwa bitandukanye vy’inganda. Amatafari y’aluminium menshi-ni ubwoko bw’ikintu gishobora guhangana n’umuriro kirangwa n’ivyuma vy’aluminium (Al2O3) birenze 48%. Iyo Al2O3 ishitse ku bice 90% canke birenze, bishirwa mu rwego rw’amatafari ya corundum-ubwoko butandukanye bw’amatafari y’alumina menshi atanga ubushobozi budasanzwe bwo guhangana n’umuriro. Birabereye kumenya ko ingingo mfatirwako z’amatafari y’alumina menshi-zishobora gutandukanywa mu bihugu bitandukanye kubera ubudasa bw’ibikoresho biriho.
Nk’akarorero, mu bihugu vy’i Buraya, igitigiri gitoyi c’ibikoresho vy’umuriro vy’alumina vyinshi-bishirwa kuri 42%. Ariko mu Bushinwa, amatafari y’alumina menshi-asanzwe ashirwa mu mice itatu: Amatafari yo mu rwego rwa I arimwo Al2O3 irenga 75%; Amatafari yo mu rwego rwa II arimwo hagati ya 60% na 75% Al2O3; na matafari yo mu rwego rwa III arimwo hagati ya 48% na 60% Al2O3.
