Graphite Crucibles

Graphite Cruciblesinopa huwandu hwezvivakwa zvinovaita sarudzo yepamusoro yemhando yepamusoro-tembiricha yekushandisa, kunyanya mukunyungudika kwesimbi uye basa rekutanga. Heano iwo akakosha emidziyo zvivakwa uye zvakatemwa zvinotsanangura mashandiro eiyi crucibles:

1. Thermal Conductivity
   • Graphite crucibleskuratidza yakanakisa yekupisa conductivity, kuve nechokwadi chekugovera kupisa kwakafanana. Ichi chivakwa chinodzikisira nzvimbo dzinopisa uye inova nechokwadi chekunyunguduka, zvichiita kuti dzishande zvakanyanya kusimbi segoridhe, mhangura, uye aluminium.
   • Thermal conductivity inogona kusvika ku100 W/m·K, iyo iri nani kana ichienzaniswa neyechinyakare refractory zvinhu.
2. High-Temperature Resistance
   • Graphite cruciblesvanokwanisa kushingirira tembiricha yakanyanya, kusvika 1700°Cmumhepo inert kana vacuum mamiriro. Izvi zvinovabvumira kuchengetedza kuvimbika kwechimiro munzvimbo dzinoda pasina kudzikisira.
   • Aya ma crucibles anoramba akatsiga uye anopesana ne deformation pasi pekupisa kwakanyanya.
3. Yakaderera Coefficient yeThermal Kuwedzera
   • Graphite zvinhu zvine ayakaderera coefficient yekuwedzera kwekupisa(yakaderera se 4.9 x 10 ^ -6 / ° C), kuderedza ngozi yekuputika kana kupisa kwekushisa kana ichiratidzwa nekukurumidza kuchinja kwekushisa.
   • Ichi chimiro chinoita magirafu crucibles akanyanya kukodzera kune maitiro anosanganisira anodzokororwa kupisa uye kutonhora kutenderera.
4. Corrosion Resistance
   • Graphite ikemikari inert uye inopakupikisa kwakanyanya kune akawanda acids, alkalis, uye mamwe maajenti ekuora, kunyanya mukuderedza kana kusarerekera mumhepo. Izvi zvinoita kuti ma graphite crucibles ave akanaka kune ane hukasha kemikari nharaunda mukukanda simbi kana kunatsa.
   • Izvo zvinhu zvinopokana kune oxidation zvinogona kuwedzera kukwidziridzwa nekupfeka kana kurapwa kwakakosha, kuve nechokwadi chehupenyu hurefu hwebasa.
5. Electrical Conductivity
   • Seyakanaka conductor yemagetsi, graphite zvinhu zvakakodzerwa induction heat application. Iyo yakakwirira yemagetsi conductivity inogonesa kubatanidza kwakanaka neinduction masisitimu, kuve nechokwadi chekudziya nekukurumidza uye yunifomu.
   • Ichi chivakwa chinonyanya kubatsira mumaitiro anodainduction heater crucibles, inosimudzira kushanda zvakanaka mumaindasitiri akaita seakawana basa kana simbi.
6. Kuchena uye Kuumbwa Kwezvinhu
   • High-purity carbon graphite crucibles.
   • Silicon carbide graphite cruciblesSanganisa zvivakwa zvegrirahiti uye silicon carbide, zvinopa simba rakavandudzwa simba, oxidation kuramba, uye nzvimbo yakakwira yekunyungudika, yakakodzera mamiriro ekunyanyisa.
7. Durability uye Hurefu Hweupenyu
   • Isostatically yakadzvanywa graphite cruciblesvanogadzirwa kuti vave neyakajairika density uye simba, zvichikonzera kuti murege maLollespans uye akaderedza kutadza kwezvinhu panguva yekudziya kwakanyanya. Aya ma crucibles zvakare anonyanya kushingirira kukukurwa uye kukuvara kwemagetsi.

8. Kemikari Kuumbwa:

   • Kabhoni (C): 20-30%
   • Silicon Carbide (SiC): 50-60%
   • Alumina (Al2O3): 3-5%
   • Vamwe: 3-5%
9. Customizable Saizi uye Shapes
   • Yedu graphite cripment inowanikwa mune dzakasiyana siyana dzehukuru uye kugadzirisa. Kubvamadiki magirafu crucibles.
   • Graphite-lined cruciblesuye crucibles withdururira spoutsinogona zvakare kugadziridzwa kune chaiyo yekukanda zvinodiwa, kuve nechokwadi chekureruka uye kugona mukubata simbi.
