Eli nqaku lihlalutya kwiingenelo ezikhethekileyo ze-graphite SiC crucibles xa kuthelekiswa nezinye izinto ezifana negraphite ecocekileyo, i-alumina, kunye ne-iron crucibles, egxininisa izicelo zabo kumashishini ahlukeneyo.

Uzinzo oluKhethekileyo lwe-Thermal kunye nokumelana nobushushu

I-Graphite SiC crucibles ibonisa ukuzinza okungenakulinganiswa kwe-thermal kunye nokumelana nokushisa okuphezulu, okukwazi ukumelana neendawo ezitshisa njenge-1600 ° C ukuya kwi-1650 ° C. Ukunyamezela ukushisa okuphawulekayo akuvumeli kuphela ukunyibilika kweentsimbi eziphezulu zokunyibilika ezifana nobhedu, igolide, isilivere kunye nentsimbi kodwa ziqinisekisa ingqibelelo ye-crucible kunye nokuphila ixesha elide phantsi kweemeko ezishushu kakhulu. Ngokwahlukileyo, izixhobo ezifana negraphite ecocekileyo kunye ne-alumina zibonelela ngokuxhathisa kwe-thermal, zinciphisa ukufaneleka kwazo kwizicelo ezithile zobushushu obuphezulu.

Ukunyangwa kweMichiza yokuNywa

I-inertness ye-chemical inertness ye-graphite ye-SiC crucibles yenye inzuzo ebalulekileyo, ukubonelela ngokuzinzileyo ngokuchasene nokuhlaselwa okutshabalalisayo kweekhemikhali ezahlukeneyo ezibandakanyekayo kwiinkqubo zokunyibilika kwesinyithi. Olu phawu luqinisekisa ukuba i-crucible ayingcolisi ukunyibilika, uqwalaselo olubalulekileyo kumashishini apho ukucoceka kwesinyithi kubaluleke kakhulu, njengokwenziwa kwe-semiconductor kunye nokuveliswa kweepaneli zelanga. Ngelixa iicrucibles ezisulungekileyo zegraphite zikwanazo ukumelana neekhemikhali ezilungileyo, zisenokungasebenzi kakuhle kwindawo ezithile ezinomhlwa xa zithelekiswa neecrucible zeSiC zegraphite.

I-High Thermal Conductivity yokuNyibilika ngokufanelekileyo

I-thermal conductivity ephezulu ye-graphite ye-SiC crucibles iququzelela ukuhanjiswa kobushushu ngokukhawuleza kunye okufanayo, okubalulekileyo ekunyibilikeni kwesinyithi okusebenzayo kunye nokungaguqukiyo. Olu phawu lunciphisa kakhulu ukusetyenziswa kwamandla kunye nexesha lokunyibilika, ukuphucula imveliso yonke yenkqubo yokunyibilika. I-graphite crucibles ecocekileyo yabelana ngolu hlobo olunenzuzo, kodwa i-graphite ye-SiC crucibles idibanisa kunye nokuzinza okuphezulu kwe-thermal, inika inzuzo eyahlukileyo kwizicelo ezifunayo.

Izicelo kuwo wonke amaShishini

Iimpawu ezikhethekileyo ze-graphite SiC crucibles zenza ukuba zilungele uluhlu olubanzi lwezicelo ngaphaya kokunyibilika kwesinyithi. Kwishishini le-semiconductor, ukuchasana kwabo kumaqondo obushushu aphezulu kunye nokubola kweekhemikhali kubenza balungele ukuvelisa ii-silicon wafers kunye nezinye izinto ze-semiconductor. Icandelo lamandla elanga lifumana inzuzo ekusebenziseni i-graphite ye-SiC crucibles ekuveliseni i-silicon ephezulu ecocekileyo yeepaneli zelanga. Ngaphaya koko, ukuqina kunye nokusebenza kakuhle kwabo kubenze baba yinto ekhethwayo kwiilabhoratri zophando kunye nezicelo ezikhethekileyo zesinyithi, apho ukuchaneka kunye nokuthembeka kubalulekile.

Ukuqukumbela

I-graphite silicon carbide crucibles imele ukuqhubela phambili okubonakalayo kwitekhnoloji ye-crucible, enikezela ukusebenza okuphezulu kubushushu obuphezulu, ukucoceka okuphezulu, kunye neenkqubo zokunyibilika kwesinyithi. Ukuzinza kwabo okungafaniyo kwe-thermal, ukuxhathisa kweekhemikhali, kunye nokuhanjiswa kwe-thermal kwenza ukuba kube yinto ekhethiweyo yokhetho olukhethiweyo kwizicelo ezahlukeneyo zemizi-mveliso kunye nophando, ukubeka imigangatho emitsha yomgangatho kunye nokusebenza kakuhle kwesinyithi. Njengoko imizi-mveliso iqhubeka nokuvela, imfuno yemathiriyeli enokumelana neemeko ezigqithisileyo ngelixa inika umsebenzi obalaseleyo ikhula rhoqo, ibeka iicrucible ze-graphite SiC phambili kwimveliso yanamhlanje kunye nesayensi yemathiriyeli.

Olu phononongo kwiingenelo kunye nokusetyenziswa kwe-graphite SiC crucibles igxininisa ukubaluleka kwayo kwi-industry landscape yanamhlanje, inika ulwazi malunga nendima yabo ekuqhubeleni phambili ubugcisa bokuvelisa kunye negalelo kuphuhliso lomgangatho ophezulu, iimveliso ezintsha.
