Kenyelletso ea mantlha ea litene tsa letsopa tse refractory

Litene tsa letsopa li bua ka lihlahisoa tsa letsopa tse nang le litaba tsa Al2O3 tsa 30% -40% ea lisebelisoa tsa silicate tsa aluminium. Litene tsa letsopa li entsoe ka 50% ea letsopa le bonolo le 50% clinker ea letsopa le thata, tse kopantsoeng ho latela litlhoko tse itseng tsa boholo ba likaroloana. Ka mor’a ho bōptjoa le ho omisoa, li chesoa ka mocheso o phahameng oa 1300 ~ 1400 ℃. Sebopeho sa diminerale tsa litene tsa letsopa ke haholo-holo kaolinite (Al2O3 · 2SiO2 · 2H2O) le litšila tsa 6% ~ 7% (li-oxides tsa potasiamo, sodium, calcium, titanium le tšepe). Mokhoa oa ho chesa litene tsa letsopa ke haholo-holo mokhoa oa ho felloa ke metsi le ho senyeha ha kaolin ho etsa likristale tsa mullite (3Al2O3 · 2SiO2). SiO2 le Al2O3 ka setene sa letsopa li theha silicate e tlaase e qhibilihisang e nang le litšila nakong ea ts’ebetso ea ho thunya, e pota-potileng likristale tsa mullite.

Litene tsa letsopa ke lihlahisoa tse fokolang tsa acidic, tse ka hanang ho khoholeha ha acidic slag le khase ea acid, ‘me li na le khanyetso e fokolang ho lintho tsa alkaline. Litene tsa letsopa li na le thepa e ntle ea mocheso ‘me li hanyetsana le serame se potlakileng le mocheso o potlakileng.
