Pali mitundu iwiri ya zipangizo zopangira aluminiyamu, imodzi ndi "fast ufa" yopangidwa ndi trialumina kapena Bayer stone, ndipo ina imapangidwa ndi aluminiyamu kapena aluminiyumu mchere kapena zonse nthawi imodzi.
X, ρ-aluminium ndi kupanga X, ρ-alumina
X, ρ-alumina ndiye chinthu chachikulu chopangira mipira ya aluminiyamu, kapena FCA mwachidule.Ku China, amatchedwa "fast release powder" chifukwa cha ufa wa alumina wopangidwa ndi njira yowonongeka mofulumira.
X,ρ-alumina inapezeka mu 1950 ndipo inatsimikiziridwa ndi ASTM mu 1960. M'zaka za m'ma 1970, x ndi Ulaya.Chinsinsi cha X, ρ -alumina teknoloji ndi kutaya madzi m'thupi mofulumira, nthawi zambiri mumadzi otsekemera a bedi, kumene kutentha kwa bedi kumayendetsedwa ndi mpweya woyaka kapena madzi.Mu 1975-1980, Tianjin Institute of Chemical Makampani bwinobwino anayamba kuyimitsidwa Kutentha Kutentha kudya anavula luso kupanga ndi makhalidwe a luso Chinese.Anagwiritsa ntchito chuluni riyakitala, anawonjezera youma ndi wosweka aluminiyamu hydroxide, ndi kupanga osakaniza X-alumina ndi ρ-alumina ndi kung'anima Kuwotcha 0.1 ~ 10s mu ng'anjo mofulumira kutaya madzi m'thupi.
