Kwi-metallurgy kunye nesayensi yezinto eziphathekayo, i i-graphite cruciblesisixhobo esiyimfuneko. Lilungu elibalulekileyo kwiinkqubo ezifuna ukunyibilika, ukugalelwa, okanye ukunyangwa kobushushu kumaqondo obushushu aphezulu kakhulu. Ngokungafaniyo nezinye izixhobo, igraphite inomdibaniso owahlukileyo we-thermal, iikhemikhali, kunye neempawu ezibonakalayo ezenza kube lolona khetho lufanelekileyo kwizicelo ezifunwayo. Eli nqaku liza kuphonononga ukuba kutheni i-graphite crucible ekumgangatho ophezulu ililitye lembombo leenkqubo zemizi-mveliso yanamhlanje, ukusuka kwisinyithi esixabisekileyo ukuya kwimveliso yesemiconductor.

Kutheni i-Graphite Crucible lolona khetho lulungileyo kwiShishini lakho

Ukukhetha imathiriyeli efanelekileyo ye-crucible sisigqibo esisisiseko esichaphazela umgangatho wemveliso yakho yokugqibela kunye nokusebenza kakuhle kwemisebenzi yakho. Nasi isizathu sokuba igraphite ivelele:

• Ukumelana neThermal okuKhethekileyo:Igraphite inokumelana namaqondo obushushu angaphezu kwe 3000°C (5432°F) kwiindawo ezingaxutywanga neoxidizing. Oku kuyenza igqibelele ukunyibilikisa uluhlu olubanzi lwemathiriyeli, kubandakanya igolide, isilivere, i-aluminiyam, kunye neengxubevange ezahlukeneyo, ngaphandle kokonakala okanye ukwaphuka.
• I-Superior Thermal Conductivity:Ubuchule obugqwesileyo begraphite bokuqhuba ubushushu buqinisekisa ukuba ubushushu busasazwa ngokulinganayo kuyo yonke i-crucible, ekhokelela ekunyibilikeni okukhawulezayo nangaphezulu. Oku akukhawulezi nje kuphela inkqubo kodwa kunciphisa ukusetyenziswa kwamandla.
• Ukungangeni kweMichiza:I-graphite ixhathisa kakhulu kuhlaselo lweekhemikhali ukusuka kwiintsimbi ezininzi ezityhidiweyo kunye nezixhobo ezonakalisayo. Oku kungasebenzi kubalulekile ekugcineni ubunyulu bezinto ezinyibilikisiweyo, ukuthintela ukosuleleka okunokubeka esichengeni umgangatho wemveliso yokugqibela.
• Ukwandiswa kobushushu obuphantsi:Ipropati ephambili yegraphite yi-coefficient yayo ephantsi yokwandiswa kwe-thermal. Oku kuthetha ukuba ayisayi kwanda okanye ikhontrakthi kakhulu xa ishushu kwaye ipholile, ikhusela iintanda kunye nomothuko we-thermal oqhelekileyo kwezinye izinto ezinqamlekileyo.
• Iinkcazelo ngeempawu zokuzithambisa:Ukuthambisa kwendalo kwegraphite kwenza kube lula ukuyiphatha kwaye inceda ukuthintela izinto ezinyibilikayo ukuba zingabambeleli kwiindonga ezikroliweyo, ukwenza lula inkqubo yokuphosa kunye nokwandisa ubomi be-crucible.

Izinto eziphambili ekufuneka ziqwalaselwe xa ukhetha i-Graphite Crucible

Ukukhetha okulungileyoi-graphite crucibleibalulekile kwisicelo sakho esithile. Nika ingqalelo kule miba iphambili ukuze uqinisekise ukuba ufumana owona msebenzi ubalaseleyo.

1. IBanga leGraphite kunye nobunyulu:
   • Ukucoceka kwegraphite kubalulekile kwizicelo ezibandakanya izinto ezicocekileyo. Jonga amabanga afana negraphite ye-isostatic ephezulu yococeko lwesemiconductor okanye ukunyibilika kwentsimbi exabisekileyo.
   • Amabanga ahlukeneyo anika amanqanaba ahlukeneyo oxinaniso, amandla, kunye nokuhanjiswa kwe-thermal.
2. Ubungakanani kunye neMilo:
   • Umthamo oBonelekileyo:Qinisekisa umthamo wezinto ozifunayo ukuze unyibilike. Kubalulekile ukukhetha i-crucible enomthamo ofanelekileyo ukuhambelana nobungakanani bebhetshi yakho.
   • Ubume:Iimilo ezisemgangathweni ziquka i-conical, i-cylindrical, kunye noyilo olukhethekileyo lweziko okanye izicelo ezithile.
3. Ubume beSicelo:
   • Umoya:I-graphite i-oxidize phambi kwe-oxygen kwiqondo lokushisa eliphezulu. Ukusetyenziswa okungaphezulu kwe-500 ° C (932 ° F), umoya wokukhusela (umzekelo, i-argon, i-nitrogen) okanye i-vacuum furnace iyafuneka ukukhusela ukuwohloka.
   • Izinto eziza kunyibilikiswa:Iintsimbi ezinyibilikisiweyo ezahlukeneyo zinokuba nentsebenziswano eyodwa kunye negraphite. Qinisekisa ukuba ibakala olikhethayo liyahambelana nemathiriyeli yakho ukuthintela ukosuleleka.
