Go na le mekgwa ye mentši ya go lokišetša aluminiamo hydroxide, go swana le mokgwa wa Bayer, mokgwa wa soda kalaka ya go sinter, mokgwa wa ammonium bicarbonate, bj.bj. Ge e le gabotse, karabelo ya alumina gape ke mokgwa wo mobotse wa go lokišetša. tshepedišo ye e itšego ya karabelo ke ye e latelago:
Ka lebaka la aluminium oxide ke amphoteric oxide hore ho thata ho qhala ka metsing, 'me aluminium hydroxide ke amphoteric hydroxide hore ho thata ho qhala ka metsing. ba ka qhala ka diesiti matla le metheo e matla, empa eseng qhibidiha ka ammonia (bokoa motheong) soluble ha e sa eketsa (weluak) ka tsoa ka ho latela (Weak}
1. Hlatswa aluminium oxide ka gare ga esiti ya sebabole go hwetša tharollo ya sulfate ya aluminiamo, ke moka o tsenye ammonia ye e fetišago go tharollo ya sulfate ya aluminiamo go hwetša aluminiamo hydroxide precipitate, yeo e ka sefiwago, ya hlatswiwa, le go omišwa.
Al2o 3+3H2SO 4=Al2 (SO4) 3+3H2O .
AL2 (SO4)3+6NH 3.H2O =2 AL (OH)3↓ *+3(NH4) SO4.
2. Hlatswa aluminiamo oxide ka gare ga sodium hydroxide go hwetša tharollo ya metaaluminate ya sodium, gomme ka morago o fetiše khaponetaeoksaete ye e fetišago ka gare ga tharollo ya metaaluminate ya sodium go hwetša hydroxide ya aluminiamo, yeo e ka akgofišwago, ya sefa, ya hlatswiwa, le go omišwa.
Go swanetše go lemogwa gore nakong ya tshepedišo ya go lokišetša, morero wa go oketša meetse a ammonia a feteletšego le khaponetaeoksaete ke go kgonthišetša gore alumina e ka fetošetšwa ka mo go feletšego go aluminiamo hydroxide go hwetša setšweletšwa se se hlwekilego. .
