2. **Ukusabela kobushushu obuphezulu kakhulu**
Ezinye iintshukumo zeekhemikhali zifuna amaqondo obushushu aphezulu kakhulu. Umzekelo, xa uvelisa ioksijini, i-potassium superoxide kufuneka ifudunyezwe ibe ngaphezulu kwe-1000°C. I-graphite crucible inokumelana namaqondo obushushu aphezulu, iqinisekisa inkqubela phambili egudileyo yovavanyo.
3. **I-Corrosion resistance**
Kwiimpendulo ezenziwe nge-asidi eyomeleleyo okanye iziseko, iiglasi eziqhelekileyo zonakaliswa lula, kodwa iicrucibles zegraphite zinokumelana ne-corrosion elungileyo kwaye zinokuzenza ngokukhuselekileyo ezi mpendulo.
### 2. Ukusetyenziswa kwinkalo yesinyithi
1. **Ukunyibilika kobushushu obuphezulu**
I-graphite crucibles isetyenziswa ngokubanzi kwiimvavanyo zokunyibilika kobushushu obuphezulu kwintsimi ye-metallurgical. Ngokomzekelo, xa ulungisa iintsimbi, kufuneka zifudunyezwe ngaphezu kwendawo yazo yokunyibilika. I-graphite crucible inokutshisa ngokuzinzileyo kwaye igcine ubushushu obufunekayo.
2. **Ukuxutywa kwezinto**
Kwezinye iimvavanyo ze-metallurgical, izinto kufuneka zongezwe kwintsimbi etyhidiweyo yokuxuba. I-graphite crucible ayigcini nje kuphela ukushisa okuphezulu kodwa iqinisekisa inkqubela phambili yenkqubo yokuxuba.
3. **Uvavanyo olukhethekileyo lweMetallurgical**
Ezinye iimvavanyo ezikhethekileyo zifuna ukuba izikhongozeli zihlale zizinzile kumaqondo obushushu aphezulu, kwaye i-graphite crucibles lukhetho olufanelekileyo kwezo zikhongozeli ezizinzileyo ezinobushushu obuphezulu.
### 3. Usetyenziso kwindawo yombane
1. **Unyango lobushushu obuphezulu**
Xa kusenziwa izixhobo zesemiconductor, iiwafers zesilicon kufuneka zifudunyezwe kumaqondo obushushu angaphezu kwe-1,000.°C. I-graphite crucible inokubonelela ngeendawo ezifunekayo zokushisa okuphezulu ukuze kuqinisekiswe ukugqitywa kakuhle kwamanyathelo enkqubo.
2. **Ubushushu obuphezulu be-sintering**
Ukuze kuphuculwe ukusebenza kwamacandelo e-elektroniki, i-sintering yobushushu obuphezulu iyafuneka. I-graphite crucible inokusebenza ngokuzinzileyo phantsi kweemeko zobushushu obuphezulu kwaye sisikhongozeli esifanelekileyo sokuntywila.
3. **Uvavanyo olukhethekileyo lwe-Electronic**
Kuvavanyo olukhethekileyo lwe-elektroniki, uzinzo oluphezulu lobushushu be-graphite crucible iyenza ibe sisikhongozeli sovavanyo esiyimfuneko.
###4. Izicelo kwintsimi yovavanyo lobushushu obuphezulu
1. **Unyango oluphezulu lobushushu bezinto eziphathekayo **
Xa ulungiselela izinto ze-ceramic, i-powder ye-ceramic kufuneka ifudunyezwe ngaphezu kokushisa kwe-sintering. Iicrucibles zegraphite zisebenza kakuhle kakhulu kuyo yonke inkqubo yokufudumeza kunye nokugcinwa kobushushu.
2. **Uphuculo lokusebenza**
Ezinye izinto zifuna unyango oluphezulu lobushushu ukuphucula iimpawu zabo. Umzekelo, xa ulungiselela idayimani, umthombo wekhabhoni kufuneka ufudunyezwe ube ngaphezulu kwe-3000°C. I-graphite crucible inokusebenza ngokuzinzileyo kwiqondo lokushisa eliphezulu, liqinisekisa ukuphuculwa kwezinto zokusebenza.
3. **Isikhongozeli sokulinga ubushushu obuphezulu**
Kwiimvavanyo zobushushu obuphezulu, i-graphite crucible sisikhongozeli esiyimfuneko, kwaye ukuzinza kwayo okuphezulu kobushushu buqinisekisa inkqubela phambili yovavanyo.
Njengesixhobo esisebenzayo sovavanyo kwiinkalo ezininzi, i-graphite crucible idlala indima engenakuthathelwa indawo kwiindawo ezahlukeneyo zobuchwephesha kunye nezibonelelo zayo ezizodwa. Ingaba kwi-chemical reactions, i-metallurgical smelting, i-electronic processing, okanye iimvavanyo eziphezulu zokushisa, ii-graphite crucibles zinika isiqinisekiso esiqinileyo sophando lwezenzululwazi kunye nokuveliswa kwemveliso kunye nokusebenza kwabo okuphezulu.
