3. I-Synthesis crucible: isetyenziselwa ukudibanisa kunye nokulungiselela izinto ezicocekileyo, ezifana nezixhobo ze-semiconductor, izinto ze-ceramic, njl.
4. I-vacuum crucible: ilungele ukufudumeza kunye nokunyibilika kwindawo yokucoca, ngokukodwa isetyenziselwa ukulungiswa kwezinto ezikhethekileyo kunye ne-smelting ye-high-purity metal.

Isixhobo sokwenza i-graphite crucible inokumelana nokushisa okuphezulu kunye nokuzinza kweekhemikhali. Ingasetyenziselwa kwiqondo lokushisa eliphezulu ngaphandle kokuguqulwa okanye umonakalo ngenxa yokushisa okuphezulu. Kwangaxeshanye, i-graphite crucible inokumelana ne-corrosion egqwesileyo kwaye inokumelana ngokufanelekileyo nokukhukuliseka kwezinto ezahlukeneyo zeekhemikhali, ngaloo ndlela iqinisekisa umgangatho wokwenziwa kwezixhobo ze-semiconductor.

Zeziphi ezona zicelo ziphambili zeecrucible zegraphite kwisemiconductor?

Kwinkqubo yokuvelisa i-semiconductor,iicrucibles zegraphitezisetyenziselwa ikakhulu ukuthwala kunye nokukhusela amacandelo e-semiconductor, kwaye zinokugqithisela ngokufanelekileyo ubushushu kunye nezangoku. Ngokusebenzisa i-handle kunye nezibiyeli ezintathu ezisisigxina ezantsi kwe-graphite crucible, inani elikhulu lamacandelo e-semiconductor linokufakwa kwi-graphite crucible ukwenzela ukuba badibane kakuhle ne-graphite crucible, ngaloo ndlela idlulise ngokufanelekileyo ukushisa kunye nokukhoyo.

Ukongeza, i-graphite crucible ingasetyenziswa njengomqhubi ofanelekileyo we-thermal kunye nombane. Ngenxa ye-conductivity ephezulu ye-thermal kunye ne-conductivity yombane, i-graphite crucible inokuqhuba ukushisa kunye nokuphuma ngaphandle kwesixhobo ukuya kumacandelo e-semiconductor ngaphakathi kwe-graphite crucible, ngaloo ndlela ifudumeza ngokufanelekileyo amacandelo e-semiconductor kunye nokulawula okwangoku.

Ukongezelela, i-graphite crucible ingaphinda isebenze njengokushisa okufanelekileyo kunye nomqhubi wombane, onokubamba inani elikhulu lamacandelo e-semiconductor, evumela ukuba izixhobo ziqhube amacandelo amaninzi ngexesha elinye, ngaloo ndlela kuphuculwe ukusebenza kakuhle kwezixhobo.

Zeziphi izicelo ze graphite crucible kushishino?

Ukuzinza kweqondo lokushisa eliphezulu kunye nokuzinza kweekhemikhali ze-graphite crucible kwenza ukuba ikwazi ukumelana nokunyibilika kwesinyithi kwiqondo lokushisa eliphezulu, ukuqinisekisa umgangatho kunye nokuzinza kwezinto ezityhidiweyo. Ngoko ke, ingasetyenziselwa ukulungiselela kunye nokunyibilika kwezinto ezahlukeneyo zetsimbi, ezifana nobhedu, i-aluminium, i-zinc, njl. Ukongeza, i-graphite crucible ingasetyenziselwa ukulungiselela kunye nokunyibilika kwezinto ze-alloy.

Ukongeza, ii-graphite crucibles nazo zinokuchasana kakuhle kokubola. Igraphite inokumelana nokugqwala okuqinileyo kwizinto ezininzi zekhemikhali kwaye inokuxhathisa ukhukuliseko lwezinto ezonakalisayo ezifana neeasidi, iialkali, kunye nezinyibilikisi. Ke ngoko, iicrucibles zegraphite zihlala zisetyenziselwa ukugcina, ukuphatha, kunye nokuhlalutya izinto eziyonakalisayo. Ngokomzekelo, kwishishini lemichiza, i-graphite crucibles ingasetyenziselwa ukuthabatha iisampulu, ukuchithwa kwezinto, kunye nokugcina i-acidic reagents. Kwi-organic synthesis, i-graphite crucibles ingasetyenziselwa unyango lwe-solvents reaction kunye ne-catalysts, kunye ne-crystallization kunye nenkqubo yokomisa yezinto eziphilayo.

Ushwankathelo

Ukongeza kwisicelo sayo kwimveliso ye-semiconductor, i-graphite crucibles nayo inokudlala indima ebalulekileyo kwi-metallurgy, casting, machine, chemistry kunye nezinye iinkalo. Ngokomzekelo, kwishishini le-metallurgical, i-graphite crucibles ingasetyenziselwa ukunyibilika nokucoca izinto zetsimbi; kwishishini lokuphosa, i-graphite crucibles ingasetyenziselwa ukunyibilikisa izinto zetsimbi kunye nokwenza iimveliso zetsimbi ezahlukeneyo; kwishishini lemichiza, i-graphite crucibles ingasetyenziswa njenge-reactors okanye izikhongozeli zokuphendula imichiza. Ngoko ke, ixabiso le-graphite crucibles alibonakali kuphela kwiinkalo zesicelo sayo, kodwa nakwindima ebalulekileyo kwimveliso yoshishino.
