Li-tubes tsa ceramic le likarolo tse nang le sebōpeho se khethehileng

Tlhaloso e Khutšoanyane:

Apara li-ceramic tse hanyetsanang tseo boholo ba tsona li entsoeng ka bonyane 90% Al2O3 ke tsona tse sebelisoang ka ho fetisisa lefatšeng kajeno.

Lihlahisoa tsa rona li entsoe ka phofo ea alumina e khethiloeng ka thata e nang le boholo ba likaroloana tse lekanang le likarolo tse tlaase tsa CaO content.Wear li-ceramics tse hanyetsanang li ka etsoa ka mochine o tloaelehileng o omileng kapa mokhoa oa ho hatella oa isostatic ebe o li tšela ka mocheso o phahameng ka sebōping.Ke lisebelisoa tse lakatsehang tsa lesela bakeng sa lisebelisoa tse phahameng tsa ho roala ka lebaka la boholo bo nepahetseng, letsoalo le phahameng, litaba tse phahameng tsa alumina, ho bata hamonate le boleng bo tsitsitseng.
