4. Isixhobo sokucoca nge-vacuum: silungele ukufudumeza nokunyibilikisa kwindawo engenamoya, sisetyenziselwa kakhulu ukulungisa izinto ezikhethekileyo kunye nokunyibilikisa iintsimbi ezicocekileyo kakhulu.
Izinto zokwenza i-graphite crucible zinokumelana kakuhle nobushushu obuphezulu kunye nozinzo lweekhemikhali. Ingasetyenziswa kubushushu obuphezulu ngaphandle kokuguquka okanye ukonakala ngenxa yobushushu obuphezulu. Kwangaxeshanye, i-graphite crucible ikwanokumelana okuhle nokugqwala kwaye inokumelana ngempumelelo nokukhukuliseka kwezinto ezahlukeneyo zeekhemikhali, ngaloo ndlela iqinisekisa umgangatho wokwenziwa kwezixhobo ze-semiconductor.
Ziziphi iindlela eziphambili zokusetyenziswa kwee-graphite crucibles kwi-semiconductor?
Kwinkqubo yokuvelisa i-semiconductor,izixhobo zokubethela zegrafayithizisetyenziselwa kakhulu ukuthwala nokukhusela izinto ze-semiconductor, kwaye zinokudlulisela ngempumelelo ubushushu kunye nomsinga. Ngesiphatho kunye neebrakethi ezintathu ezizinzileyo ezantsi kwe-graphite crucible, inani elikhulu lezinto ze-semiconductor zingafakwa kwi-graphite crucible ukuze zinxibelelane kakuhle ne-graphite crucible, ngaloo ndlela zidlulisela ngempumelelo ubushushu kunye nomsinga.
Ukongeza, i-graphite crucible ingasetyenziswa njengomqhubi wobushushu nombane ofanelekileyo. Ngenxa yokuqhuba kwayo okuphezulu kobushushu kunye nokuqhuba kombane, i-graphite crucible inokuqhuba ubushushu kunye nomsinga ukusuka ngaphandle kwesixhobo ukuya kwizixhobo ze-semiconductor ngaphakathi kwi-graphite crucible, ngaloo ndlela ifudumeza ngempumelelo izixhobo ze-semiconductor kwaye ilawule umsinga.
Ukongeza, i-graphite crucible ingasebenza njengomqhubi wobushushu nombane ofanelekileyo, onokuthwala inani elikhulu lee-semiconductor components, okuvumela izixhobo ukuba zicubungule ii-compounds ezininzi ngaxeshanye, ngaloo ndlela ziphucula ukusebenza kakuhle kwezixhobo.
Zithini izicelo ze-graphite crucible kushishino?
Uzinzo oluphezulu kubushushu kunye nozinzo lweekhemikhali ze-graphite crucible ziyenza ikwazi ukumelana nokunyibilikiswa kwesinyithi kubushushu obuphezulu, okuqinisekisa umgangatho kunye nozinzo lwezinto ezinyibilikisiweyo. Ke ngoko, ingasetyenziselwa ukulungiselela nokunyibilikisa iintlobo ngeentlobo zezinto zesinyithi, ezifana nobhedu, i-aluminium, i-zinc, njl. Ukongeza, i-graphite crucible ingasetyenziselwa ukulungiselela nokunyibilikisa izinto ze-alloy.
Ukongeza, izinto ezixutywayo zegrafiti nazo zinokumelana okuhle nokugqwala. Igrafiti inokumelana okukhulu nokugqwala kwiikhemikhali ezininzi kwaye inokumelana nokugqwala kwezinto ezixutywayo ezifana nee-asidi, ii-alkali, kunye nezinyibilikisi. Ke ngoko, izinto ezixutywayo zegrafiti zihlala zisetyenziselwa ukugcina, ukuphatha, kunye nokuhlalutya izinto ezixutywayo. Umzekelo, kushishino lweekhemikhali, izinto ezixutywayo zegrafiti zingasetyenziselwa ukucola iisampulu, ukunyibilikisa izinto, kunye nokugcina izinto ezixutywayo ze-asidi.
