Umahluko phakathi kwe-graphite silicon carbide kunye nodongwe lwe-graphite crucibles

I-graphite ye-silicon carbide crucibleskunye ne-clay graphite crucibles zinqanawa ezimbini zebhubhoratri eziqhelekileyo ezinomahluko obalulekileyo kwizinto, iipropati kunye nokusetyenziswa.

Izinto:

I-graphite silicon carbide crucible: Yenziwe ngezinto ze-graphite silicon carbide, inozinzo oluphezulu lobushushu, ukumelana nokugqwala kunye nokuhamba kakuhle kwe-thermal.
I-Clay graphite crucible: ngokuqhelekileyo yenziwe ngomxube wodongwe kunye negraphite, kunye nomxholo ophantsi wegraphite, ngokukodwa usebenzisa udongwe njengento esisiseko, kunye negraphite yongezwa ngokukodwa ukuze kuphuculwe ukuxhathisa ukushisa okuphezulu.
Ukumelana nobushushu:

I-graphite silicon carbide crucible: Iyakwazi ukumelana namaqondo obushushu aphezulu kakhulu kwaye iqhele ukusetyenziswa kwiqondo lobushushu le-1500°C ukuya kuma-2000°C okanye nangaphezulu.
I-Clay graphite crucible: Ukumelana nobushushu kuphantsi, kwaye ubushushu obuqhelekileyo bokusetyenziswa bungama-800°C ukuya kwi-1000°C. Ukugqithisa olu luhlu lweqondo lokushisa kunokubangela lula umonakalo okanye ukuguqulwa kwe-crucible.
Ukuchasa umhlwa:

I-graphite silicon carbide crucible: Inokumelana nokukhula okuphezulu kwaye inokumelana nokukhukuliseka kweekhemikhali ezinjengeeasidi kunye neealkali.
Clay Graphite Crucible: Ngenxa yesiqulatho salo sodongwe esiphezulu xa kuthelekiswa negraphite silicon carbide, isenokungaxhathisi kwiikhemikhali ezithile eziyonakalisa kakhulu.
I-Thermal Conductivity:

I-graphite silicon carbide crucible: Ine-conductivity elungileyo ye-thermal kwaye inokudlulisa ubushushu kwisampulu ngokukhawuleza nangokulinganayo.
I-Clay graphite crucible: I-thermal conductivity yayo inokuba mbi ngakumbi kune-graphite silicon carbide crucible.
Ixabiso kunye nesicelo:

I-graphite silicon carbide crucible: Ngokuqhelekileyo ibiza kakhulu, kodwa ifanelekile kwiimvavanyo kunye nokusetyenziswa okudinga ukushisa okuphezulu kunye nokuxhathisa ukubola.
I-Clay graphite crucible: Ixabiso liphantsi kakhulu, lifanelekile kwizicelo zebhubhoratri jikelele, iimeko apho iimfuno zokushisa zingekho phezulu, okanye apho iimfuno zokuxhathisa ukubola zingekho ngqongqo kakhulu.
Isishwankathelo, i-graphite silicon carbide crucibles kunye ne-clay graphite crucibles inomahluko omkhulu kwizinto eziphathekayo, ukumelana nobushushu, ukuxhathisa kwe-corrosion, i-thermal conductivity, njl. Ungabonisana nathi kwaye siya kukubonelela ngeenkonzo zobungcali.
