Sebopeho sa Libolo tsa Alumina Refractory
Libolo tsa alumina tse hanyetsang li entsoe ka AL2O3, kaolin, motsoako oa maiketsetso, kristale ea mullite le lisebelisoa tse ling. Ho ea ka mokhoa oa ho rolla le ho qapa, libolo tsa aluminium tse hanyetsang li na le melemo ea matla a phahameng, ho hanyetsa mocheso hantle, ho nkeloa sebaka le ho hloekisoa habonolo, bophelo bo bolelele ba tšebeletso le tse ling.
Ts'ebetso ea Libolo tsa Alumina Refractory
E le ho etsa libolo tsa alumina tse hanyetsang, electrode e beoa tlase ho graphite crucible, 'me arc e ka qaloa ka ho eketsa phofo e itseng ea alumina ea indasteri. Hona joale e sebetsang ke 1.0kA, motlakase ke 80 ~ 100V. Kamora ho otla, ha Al2O3 e qhibilihisoa, e jara butle-butle, ho fihlela mokelikeli oa thepa o tlala graphite crucible, mocheso oa mokelikeli oa thepa ke 2200 ~ 2300 ℃. Kamora moo, crucible e tšoloha 'me tharollo e phalla.
