Kwisayensi yesinyithi kunye nezinto eziphathekayo, isixhobo sokubethela igrafayithisisixhobo esibalulekileyo. Sisixhobo esibalulekileyo kwiinkqubo ezifuna ukunyibilika, ukuphoswa, okanye ukunyanga ubushushu kumaqondo obushushu aphezulu kakhulu. Ngokungafaniyo nezinye izinto, i-graphite inomdibaniso owahlukileyo weempawu zobushushu, iikhemikhali, kunye nezomzimba ezenza ukuba ibe lolona khetho lufanelekileyo kwizicelo ezifuna umgudu. Eli nqaku liza kuhlola ukuba kutheni i-graphite crucible esemgangathweni ophezulu isisiseko seenkqubo zanamhlanje zoshishino, ukusuka ekuphosweni kweentsimbi ezixabisekileyo ukuya ekuvelisweni kwee-semiconductor.

Kutheni iGraphite Crucible iyeyona khetho ilungileyo kwishishini lakho

Ukukhetha izinto ezifanelekileyo ezisetyenziswa ekutshiseni sisigqibo esisisiseko esichaphazela umgangatho wemveliso yakho yokugqibela kunye nokusebenza kakuhle kwemisebenzi yakho. Nantsi isizathu sokuba i-graphite ivelele:

• Ukumelana nobushushu obungaqhelekanga:I-Graphite inokumelana namaqondo obushushu angaphezulu kwama-3000°C (5432°F) kwiindawo ezingena-oxidizing. Oku kuyenza ifaneleke kakhulu ekunyibilikiseni uluhlu olubanzi lwezinto, kuquka igolide, isilivere, i-aluminium, kunye nee-alloys ezahlukeneyo, ngaphandle kokuguquguquka okanye ukuqhekeka.
• Ukuqhuba okuPhezulu kobushushu:Ubuchule obugqwesileyo beGraphite bokuqhuba ubushushu buqinisekisa ukuba ubushushu busasazwa ngokulinganayo kuyo yonke i-crucible, nto leyo ekhokelela ekunyibilikeni ngokukhawuleza nangokulinganayo. Oku akukhawulezisi nje kuphela inkqubo kodwa kunciphisa nokusetyenziswa kwamandla.
• Ukungasebenzi kakuhle kweekhemikhali:I-Graphite iyakwazi ukumelana kakhulu nohlaselo lweekhemikhali oluvela kwiintsimbi ezininzi ezinyibilikisiweyo kunye nezinto ezirhabaxa. Oku kungangeni kakuhle kubalulekile ekugcineni ubunyulu bento enyibilikisiweyo, ukuthintela ungcoliseko olunokonakalisa umgangatho wemveliso yokugqibela.
• Ukwanda kobushushu obuphantsi:Isici esiphambili se-graphite kukuba i-coefficient yayo ephantsi yokwandiswa kobushushu. Oku kuthetha ukuba ayizukunwebeka okanye inciphe kakhulu xa ishushu kwaye ipholile, nto leyo ethintela ukuqhekeka kunye nokutshayiswa kobushushu okuxhaphakileyo kwezinye izinto ezisetyenziswa ekutshiseni.
• Iimpawu zokuzithambisa:Ukuthamba kwendalo kwegraphite kwenza kube lula ukuyiphatha kwaye kunceda ukuthintela izinto ezinyibilikisiweyo ukuba zinganamatheli eludongeni lwe-crucible, okwenza kube lula inkqubo yokubumba kwaye kwandise ubomi be-crucible.

Izinto Ezibalulekileyo Ekufuneka Uziqwalasele Xa Ukhetha I-Graphite Crucible

Ukukhetha okulungileyoisixhobo sokubethela igrafayithiKubalulekile kwisicelo sakho esithile. Nika ingqalelo kwezi zinto zibalulekileyo ukuqinisekisa ukuba ufumana ukusebenza okungcono kakhulu.

1. Ibanga leGraphite kunye nokuHlanzeka:
   • Ubunyulu begrafiti bubalulekile kwiindlela ezisetyenziswayo xa kusenziwa izinto ezicocekileyo kakhulu. Khangela iindlela ezifana negrafiti ye-isostatic ecocekileyo kakhulu yokunyibilikisa i-semiconductor okanye i-precious metal.
   • Amanqanaba ahlukeneyo anika amanqanaba ahlukeneyo oxinano, amandla, kunye nokuqhuba ubushushu.
2. Ubukhulu kunye nokuma:
   • Umthamo woMkhukula:Misela ubungakanani bezinto oza kuzinyibilikisa. Kubalulekile ukukhetha i-crucible enomthamo ofanelekileyo ohambelana nobukhulu bebhetshi yakho.
   • Imilo:Iimilo ezisemgangathweni ziquka uyilo oluyi-conical, oluyi-cylindrical, kunye noyilo olukhethekileyo lwee-oven okanye usetyenziso oluthile.
3. Indawo yokusetyenziswa:
   • Umoya ongqongileyo:I-Graphite iyanyibilika xa kukho ioksijini kumaqondo obushushu aphezulu. Kwizicelo ezingaphezulu kwama-500°C (932°F), kufuneka umoya okhuselayo (umz., i-argon, i-nitrogen) okanye i-vacuum furnace ukuze kuthintelwe ukubola.
   • Izinto eziza kunyibilikiswa:Iintsimbi ezahlukeneyo ezinyibilikisiweyo zinokuba nobudlelwane obukhethekileyo negrafiti. Qinisekisa ukuba uhlobo olukhethileyo luyahambelana nezinto zakho ukuze kuthintelwe ungcoliseko.
