Carbon bonded silicon carbide crucible, inoshandiswa zvakanyanya mumarabhoritari ekupisa kwepamusoro.Aya ma crucibles anopa akasiyana mabhenefiti akadai sesimba rakakwirira uye kuramba deformation uye kutsemuka pakupisa kwakanyanya.Nekudaro, zvakakosha kuziva kuti ivo vane zvimwe zvipingamupinyi zvinoda kutariswa.
Imwe yezvakanyanya kuipa kwesilicon carbide crucibles ndeye fragility yavo.Aya ma crucibles anowanzo pwanya kana akaiswa mumagetsi kuvhunduka panguva yekushandiswa.Kana zvakuvadzwa, zvinogona kuita kuti zviedzo zvikundikane kana kukanganisa kurongeka kwedata rekuyedza.Kusagadzikana uku kunofanirwa kuverengerwa uye matanho akakodzera anotorwa panguva yekubata uye kushandiswa.
Chimwe chinokanganisa chesilicon carbide crucibles ndechekuti ivo vanowanzoita oxidation maitiro pakupisa kwakanyanya.Kana yakaratidzirwa kune tembiricha yakakwira, oxide layer inogona kuumba pamusoro peiyo crucible, iyo inogona kukanganisa mhedzisiro yekuedza.Zvakakosha kudzivirira oxidation iyi nekutora matanho ekudzivirira, zvakadai sekuvhara crucible surface nekudzivirira.
Uye zvakare, silicon carbide crucibles iri pasi pezvimwe zvisingakwanisi nekuda kwezvinhu zvakaita sekugadzira maitiro uye mutengo.Izvi zvinogumira zvinogona kudzikisira saizi, chimiro, uye kugona kweiyo crucible.Naizvozvo, vaongorori nevagadziri vanofanirwa kufunga nezvezvipimo izvi pakusarudza macrucibles kune avo chaiwo zvavanoda.
Kugadzirisa zvikanganiso zvesilicon carbide crucibles, mhinduro dzinoverengeka dziripo.Chokutanga pane zvose, kuitira kuti uvandudze hupenyu hwebasa re crucible, nzira dzinogona kushandiswa kusimbisa mutsigiri wemadziro emukati kuti iite kuti iwedzere kupfeka uye yakasimba.Izvi zvinobatsira kudzivirira kuputsika uye kuwedzera hupenyu hweiyo crucible.
Chechipiri, kuitira kudzivirira oxidation, chidziviriro chekudzivirira chinogona kuiswa pamusoro peiyo crucible.Iyi denderedzwa inodzivirira iyo crucible kubva pakuita neokisijeni pakupisa kwakanyanya, nokudaro kudzivirira kuumbwa kweiyo oxide layer.
Chekupedzisira, kukurira zvipimo zvesilicon carbide crucibles, dhizaini inogona kugadziridzwa uye yakawedzera kugadzirwa maitiro anogamuchirwa.Nekuita kudaro, maumbirwo makuru, akadzika, uye akaoma kunzwisisa anogona kugadzirwa, achibvumira kushandiswa kwezvipingamupinyi izvi muhuwandu hwakawanda hwemaseti ekuedza.Pamusoro pezvo, zvimwe zvinhu zvakaita seyakakwira-tembiricha ceramics inogona kutariswa kutsiva silicon carbide crucibles.
Mukupedzisa, silicon carbide crucibles ine zvimwe zvayakaipira, asi kushandisa kwavo murabhoritari kuchiri kubatsira zvakanyanya.Iko kuita kwese uye kuita kwakasiyana-siyana kwesilicon carbide crucibles kunogona kuvandudzwa nekutora matanho akakodzera uye optimizations kugadzirisa brittleness yavo, kukonzeresa kune oxidation, uye zvisingakwanisi.Vatsvagiri nevagadziri vanofanirwa kunyatso funga izvi zvinhu pakusarudza yakakwirira-tembiricha yekuyedza crucibles.
