Ma Crucibles Odalirika Osungunula ndi Kuponya

Ili ndi mawonekedwe a kukana kutentha kwambiri, kukhathamiritsa kwamphamvu kwamafuta, kukana kwa dzimbiri komanso moyo wautali wautumiki.Pogwiritsa ntchito kutentha kwakukulu, coefficient of thermal expansion ndi yaying'ono, ndipo imakhala ndi zovuta zina zomwe zimakana kuzizira kofulumira komanso kutentha kofulumira.Ili ndi kukana kwamphamvu kwa dzimbiri ku njira za acidic ndi zamchere, imakhala ndi kukhazikika kwamankhwala abwino kwambiri, ndipo sichita nawo zochitika zilizonse zamankhwala panthawi yosungunula.Khoma lamkati la graphite crucible ndi losalala, ndipo madzi osungunuka achitsulo si ophweka kutayikira ndi kumamatira ku khoma lamkati la crucible, kotero kuti madzi achitsulo ali ndi madzi abwino komanso otayika, ndipo ndi oyenera kuponyera nkhungu zosiyanasiyana.
