Tlhaloso e Khutšoane

Brown Fused Alumina e hlahisoa ke ho qhibilihisoa ha Calcined Bauxite ka seboping sa motlakase sa arc mocheso o fetang 2000 ° C. Ts'ebetso ea ho tiisa butle e latela fusion, ho hlahisa likristale tse thibelang. Thuso e qhibilihisang ho tlosa sebabole le khabone e setseng, Taolo e tiileng holim'a maemo a Titania nakong ea ts'ebetso ea ho kopanya e tiisa ho tiea ho hoholo ha lijo-thollo.

Ebe crude e pholisitsoeng e ea siloa hape, e hloekisoa litšila tsa makenete ka li-separators tse matla haholo ebe li aroloa ka likaroloana tsa boholo bo moqotetsane ho lumellana le ts'ebeliso ea ho qetela. Mehala e inehetseng e hlahisa lihlahisoa bakeng sa lits'ebetso tse fapaneng.
