Phapang ke efe lipakeng tsa alumina e phahameng refractory setene le letsopa refractory setene?

1. Boleng ba lik’hemik’hale ba PH ea litene tse phahameng tsa alumina ke tsa litene tse sa nke lehlakore le tsa alkaline, ‘me litene tsa letsopa ke tsa litene tse sa nke lehlakore le acid.

2. Ntle le ts’abo ea mocheso oa litene tse phahameng tsa alumina, litene tse ling tse haelloang ha li tšoane le litene tsa letsopa. Ka kakaretso, kahong ea li-kilns le lisebelisoa tse ling tsa mocheso, haeba litene tsa letsopa li ka sebelisoa, litene tse phahameng tsa alumina li sebelisetsoa ho haha.

3. Litene tse phahameng tsa alumina tse qhekellang ke litene tsa aluminium silicate tse emereng tse nang le litaba tsa Al2O3 tse kholo ho feta 48%. Litene tse hahiloeng ka letsopa li bua ka lihlahisoa tsa letsopa tse nang le Al2O3 tse nang le lisebelisoa tsa silicate tse 30% -40%.

4. Litene tsa letsopa li na le ts’ebetso e ntle ea mocheso ‘me li hanela serame se batang le mocheso o potlakileng; mocheso o chesang oa litene tse phahameng tsa alumina o ipapisitse le ts’ebetso ea ho sintering ea lihlahisoa tse tala tsa bauxite.

5. Thempereichara e nolofatsang ea litene tse phahameng tsa alumina tse hanyetsang e fapana le litaba tsa Al2O3. Litene tsa letsopa li na le mocheso o tlase o fokotsang, li fokotseha maemong a phahameng a leholimo, ‘me li na le mocheso o futhumatsang ka 15% -20% ho feta litene tsa silika.
