I-silicon ye-carbide ye-ceramic crucibleyenziwe nge-silicon carbide kwaye sisixhobo esiqhelekileyo sobushushu obuphezulu.I-silicon ye-carbide ye-ceramic crucibleinozinzo olubalaseleyo lobushushu obuphezulu, ukuxhathisa okugqwesileyo kwe-corrosion kunye ne-coefficient yokwandisa i-thermal ephantsi, eyenza ukuba ikwazi ukumelana noxinzelelo olugqithisileyo lobushushu kunye nokukhukuliseka kweekhemikhali kwiindawo ezinobushushu obuphezulu. Isetyenziselwa indawo yokuhlala isampuli kunye nokucubungula kwiimvavanyo okanye iinkqubo zoshishino ezifana nokunyibilika, ukutshisa, ukunyanga ubushushu kunye nokuphendula kweekhemikhali phantsi kweemeko eziphezulu zokushisa.
Yethui-silicon carbide crucibleyenziwe ngokucofa okuphezulu kwe-isostatic kwaye ine-conductivity elungileyo ye-thermal kunye nokumelana nobushushu obuphezulu. Kwinkqubo yokusetyenziswa kobushushu obuphezulu, i-coefficient yokwandiswa kwe-thermal incinci, kwaye inobunzima obuthile bokumelana nokufudumala kunye nokupholisa ngokukhawuleza. Inokumelana ne-corrosion eyomeleleyo kwisisombululo se-asidi kunye ne-alkali kunye nokuzinza okuhle kakhulu kweekhemikhali. Imodeli ethile ingenziwa ngokwezifiso ngokuzoba kunye nesampuli, kwaye izinto eziphathekayo ziyigraphite yasekhaya kunye negraphite ethunyelwa ngaphandle ukuhlangabezana neemfuno ezahlukeneyo zabathengi.
Izinto eziphambili ze-graphite crucible ziyi-graphite, i-silicon carbide, i-silica, udongwe olunqabileyo, i-pitch, kunye ne-tar, njl.
