Kukho iintlobo ezimbini zezinto eziluhlaza zokuvelisa i-alumina esebenzayo, enye "yi-powder esheshayo" eveliswa yi-tricumina okanye ilitye le-Bayer, kwaye enye iveliswa nge-aluminiyam okanye i-aluminium ityuwa okanye zombini ngaxeshanye.
X,ρ-alumina kunye nokuveliswa kwe-X,ρ-alumina
X, ρ-alumina yeyona nto iphambili ekrwada ukuveliswa kweebhola ze-alumina ezisebenzayo, okanye i-FCA ngokufutshane. E-China, kubizwa ngokuba "umgubo okhawulezayo wokukhululwa" ngenxa ye-alumina powder eveliswa yindlela yokukhupha ngokukhawuleza.
I-X, i-ρ-alumina yafunyanwa ngo-1950 kwaye yaqinisekiswa yi-ASTM ngo-1960. Kwiminyaka ye-1970, x kunye neYurophu. Isitshixo kwi-X, ρ -alumina iteknoloji yokuphelelwa ngamanzi emzimbeni ngokukhawuleza, ngokuqhelekileyo kwi-reactor yebhedi ene-fluidized, apho ubushushu bebhedi bulawulwa yigesi yokutsha okanye ulwelo. Ngo-1975-1980, iZiko leTianjin loShishino lweMichiza liphuhlise ngempumelelo ukufudumeza okunqunyanyiswayo ngokukhawuleza ukuhlutha itekhnoloji yemveliso eneempawu zobuchwepheshe baseTshayina. Yasebenzisa i-cone reactor, yongeza i-aluminium hydroxide eyomileyo kunye netyunyuziweyo, kwaye yenza umxube we-X-alumina kunye ne-ρ-alumina nge-flash roasting 0.1 ~ 10s kwisithando somlilo esikhawulezayo.
